Crash a few second after opening - Ubuntu 22.10

[ahangarha]

Recently I decided to use Element from flatpak. I could install, sign in, and verify my account but the app crashes a few seconds after I open it.

This is the terminal log when I run the app from terminal:

LaunchProcess: failed to execvp:

Operating system

Ubuntu 22.10 (Wayland)

Application version

1.11.17

How did you install the app?

https://flathub.org/apps/details/im.riot.Riot

Homeserver

matrix.org

This might be relevant in some way: I am doing this from Iran. Ensure this might be because of either some internet filtering from the Iranian government (though I can use the app without any issue on my phone and even in those few seconds after launching the app, I can see my messages) or because of some filtering from the servers against Iranian IPs. Even in such cases, we shouldn't experience crashes.

Again, this is just a side note which might be helpful for debugging.

Known issue. It seems to be a bug that happens when message caching is enabled. To disable it: Settings > Security & Privacy > Message Search (Manage) > Disable.

[ahangarha]

I quickly made this change and so far it is working fine.

If this is something to be fixed on the main project, please let me know how to report this.

[ripper81]

I don´ t even get this far because the app crashes within seconds. Please release a fix for it.

I've finally found some time to look into this issue, sadly not with the wanted success. It's clear that it originates from the search code. So far I could isolate, that it doesn't seem to be related to the sqlcipher library itself and not to zypak wrapper.

For now, the only way to avoid it is to drop search support for encrypted messages. However I don't know how large the number of impacted user by the crashes is, and I don't know how many people use search for encrypted conversations. Therefore the trade-off is hard to calculate.

[telometto]

@SISheogorath Does this happen on the non-flatpak version too? Could be an issue with the flatpak. It's odd, however, because up until a few months ago, everything seemed to work fine; even with the indexing enabled. By the way, maybe you know which parameter/conf-file @ripper81 could make changes to in order to allow him to open the app? Where can one disable indexing without accessing the GUI?

-Cheers :)

[SISheogorath]

Sadly no, I couldn't find any way to disable it, without using the UI.

This isn't a solution for the bug, but if you want to disable message caching on an Element flathub app that is already in a crash cycle:

1. Open the app
2. Quickly click on the logout option/button/hyperlink as the app is starting up
3. Sign in again (perhaps skip the 'verify session' step)
4. Click on your user Icon at the upper left of the Element window
5. Select the 'Security & Privacy' menu shortcut (can also find this option via 'Settings')
6. Disable 'Message Search'

That process let me get element desktop working again on my computer.

If you can't log out, you could also delete the data directory at ~/.var/app/im.riot.Riot.

Maybe the flatpak shouldn't include the matrix-seshat native dependency if it is known to be incompatible with it?

[SISheogorath]

Since this flatpak is only repacking upstream, that's not really an option. The dependencies we built as part of this flatpak, namely sqlcipher, has been tested to be replaced with the same sqlcipher package that upstream uses, however, this didn't solve it.

Only removing sqlcipher entirely would be an option which "breaks" matrix-seshat and disables search support entirely. But this also results in a bunch of places showing "Hey, how about you download the Element Desktop App", which might causes more confusion than it helps.

Confirming on Fedora 37.

Just wanted to add this is happening on flatpak Version: 1.11.23 on Gnome (43.2) Wayland. (Debian Testing). It happens both in full screen and half screen modes.

FWIW this is seems to be a duplicate of https://github.com/vector-im/element-desktop/issues/648
