Steps to reproduce

Install new version Click 'Finish' window with 'start' option active Receive 'crashed' notice

Additional context

I re-downloaded and re-installed in case of a download glitch, but there was no apparent change. When completing this form I noted 4.4 had loaded despite the crash report, but now shows 14 downloads against 300 that were previously listed.

glassez commented 2 years ago

This crash is due to misconfiguration. Some previously added torrent has assigned category that is missed (doesn't exist in configuration file). Did you remove qBittorrent.ini before run updated qBittorrent? What version did you use before?

What version did you use before?

Qt 6.2.2 version tried but also crashes.

I mean what qBittorrent version did you use before v4.4?

gazumped commented 2 years ago

Thanks for the quick responses.
I used 4.3.9 previously. I reverted to that today, and have 339 current torrents, 322 completed. I did not remove qBittorrent.ini before running the new version - I didn't realise that was required. If there's a 'category' problem, would deleting all categories via right-click help? If not, how do I clear current entries?

No. On contrary it can cause the same crash as you have.

rumanzo commented 2 years ago

I have similar error after reboot for update windows. I tried reinstalling qt6 version to qt5 and got no change.

This crash is due to misconfiguration. Some previously added torrent has assigned category that is missed (doesn't exist in configuration file). Did you remove qBittorrent.ini before run updated qBittorrent? What version did you use before?

I have the exact same issue when upgrading from 4.3.9 to 4.4 in Win10. qBittorrent.ini is present in the AppData\Roaming\qBittorrent folder. Checked all torrents and can't find any with 'missing' categories, although some are 'Uncategorised'. Any ideas how to resolve this? Many thanks.

gazumped commented 2 years ago

Any ideas how to resolve this? - Not yet. Can't see any local issues that might be the problem. Back to 4.3.9 for the moment.

vangeliis commented 2 years ago

Perhaps the issue lies with the categories.json file? In my case there is a mismatch between the categories in my client and those in the categories.json file. Seems like when a category is added and/or deleted the categories.json isn't updated according? Could this be causing v4.4 to crash?

categories.json is used by v4.4+. Previously categories were stored in qBittorrent.ini. When you run qBittorrent v4.4+ and there is no categories.json file it "thinks" that it runs first time after update from previous release and performs "upgrade path", i.e. it imports categories from qBittorrent.ini. So if you run v4.4 then downgrade to v4.3, create some categories with it and assign these categories to torrents, then run v4.4 again (so it doesn't apply upgrade anymore because of existing categories.json) there are missing categories.

That's exactly what has happened in my case! Well spotted. Can I assume that deleting the categories.json and re-installing v4.4.0 should work without qBittorrent crashing at startup?

gazumped commented 2 years ago

New here, so I haven't found out how to add the previous comments before, but thanks @glassez - I renamed my categories.json to categories.json.old and will try updating again later... more here if it works!

Can I assume that deleting the categories.json and re-installing v4.4.0 should work without qBittorrent crashing at startup?

Yes. Unless you added some categories when run v4.4 previously. Anyway you'll be able to add some categories in categories.json manually.

FYI, I'm going to add auto-recovery of such "lost" categories. But unfortunately it most likely won't be ready for v4.4.1 release.

I can confirm that deleting/renaming the categories.json and re-installing v.4.4.0 works without crashing. Looks like when downgrading from 4.4 to 4.3.9 the uninstaller didn't remove the categories.json as one would expect?

glassez commented 2 years ago

Does uninstaller affect any user data? I suppose it shouldn't. Anyway it isn't a valid solution. There can be some categories added in v4.4 so they will be missing after downgrade. Downgrade can lead to "undefined behavior" generally so we never recommend it in any way other than using full backup of configuration/data from the same version you want downgrade to.

We got to the bottom of this issue which is great, many thanks. Hopefully in future releases the categories can be 'saved/restored' when downgrading.
