• If I start keepassxc, it freezes and the nwg-panel freezes as well.
• If both applications are in frozen state, they can't even be stopped by CTRL-C
• If I stop keepassxc in this state by sending KILL signal (pkill -9 keepassxc), the nwg-panel bails out with the following exception:

• After stopping keepassxc the nwg-panel seems to continue just fine.

I don't think it's a panel bug. KeePassXC tray icon seems to be Wayland incompatible. See
keepassxreboot/keepassxc#6502 and more results for the "KeePassXC tray icon wayland" Google search. Actually it happens to crash Wayland at all in my sway session.

Maybe there's a problem with Qt based applications not behaving correctly, but there is no reason that the panel completely hangs because of that IMHO.

BTW: Waybar works without problems.

[nwg-piotr]

Maybe it's possible to workaround in some way, but for now I have no idea. I'll get back to it when I have more time.

I have the same problem for nextcloud-client. It freezes, as nwg-panel does immediatly. Not logs, but I can stop nextcloud-client using <Ctrl+c>. I wonder if I should create a new issue for this, because it seems to be a general issue with QT icons in nwg-panel ?

[varac]

This is really blocking, since I cannot use the nextcloud-desktop under nwg-shell. Anything I could do to help here ?

[varac]

@nwg-piotr I created #165 for the NC issue

[nwg-piotr]

Ok, but for now I have no idea where to start from.
