Man, you get so many crashes in so many reconnecting accounts! Thank you for reporting them all. :)

EionRobb commented 2 years ago

Thanks again. Hopefully this latest commit helps?

bodqhrohro commented 2 years ago

I'll try it, thanks.

Worth noting that before this crash it popped out lots of tabs for channels with no activity, which itself is not healthy. 2022-01-30-132249_1366x768_scrot 2022-01-30-133342_1366x768_scrot

pabs3 commented 2 years ago

@bodqhrohro so are you saying the patch didn't fix the issue for you?

bodqhrohro commented 2 years ago

@pabs3 it should, yet I cannot confirm it because I don't know the exact reproduction conditions ;) At least, it did not occur again yet.

pabs3 commented 2 years ago

Ok, thanks for the info. Guess I should update the Debian package then.

-- bye, pabs

If I wasn't patient enough, I would suppose it's a bug in libpurple itself:
