Arch Linux

Description:
OnionShare's chat functionality is broken in 2.5-1.
The app does not crash but becomes pretty much unusable after clicking the 'Start
Chatting' item.

Downgrading to 2.4-1 revives the lost functionality but has several security issues that
2.5 supposedly fixed (cfr. https://github.com/onionshare/onionshare/releases/tag/v2.5).
I only downgraded to check the chat feature, which I never used before, and wouldn't
recommend that obviously.

Additional info:
* package version(s)
$ pacman -Q onionshare
onionshare 2.5-1
* config and/or log files etc.
Outout is available in the upstream bug report, but here it is:
$ onionshare -v
[...]
