Hi! Could you please run wf-panel under gdb and report the stacktrace of the thrown exception? I am pretty sure this is a problem about notifications widget.

Also this issue should be transferred to wf-shell repo.

Same issue on my site.
Recompiled the wayfire and wf-panel (both in version 0.9.0) with CFLAGS="-ggdb3" and splitdebug (Gentoo way):

Quit anyway? (y or n) y

EDIT: If I disable the "Show desktop notifications for sound changes" (translated), the issue does not appear.

Hi, could you please check whether #284 fixes the issue?

[bell07]

Confirm the patch in #284 avoid the panel crash if spotify play is started first time. In addition it solves my issue the keepassxc tray icon was not shown.

But now spotify freezes for ~30 seconds if play is started first time. The music is playing, but cannot be controlled, paused or window be closed. After ~30 seconds (time measured with timer) the spotify gets useable again.
Still have to disable the notifications in spotify to avoid this freeze.

[NamorNiradnug]

In addition it solves my issue the keepassxc tray icon was not shown.

The patch is not related to the tray widget at all, probably you've done something else in order to fix it.

But now spotify freezes for ~30 seconds if play is started first time. The music is playing, but cannot be controlled, paused or window be closed. After ~30 seconds (time measured with timer) the spotify gets useable again.

Hmm, interesting... Sounds like a Spofify's issue to me. Do I get it right:

• you open Spotify
• start playing some music
• the music is playing, the notification is there, but Spotify's UI is freezed
• then it unfreezes and playing next tracks is fine
  ?

Doesn't spotify log anything helpful?

[NamorNiradnug]

By the way, does it work fine with any other notification manager in the wild (such as https://github.com/dunst-project/dunst)?

[bell07]

You are right, the keepassxc issue is not solved yet. After reboot the tray icon is away again...

• I open Spotify
• I start paying music
• The Notification does NOT appear
• Before the patch the Panel was crashed at this point
• After the patch I get a freeze in spotify.
• Freeze means: The time remains at 0:00 and the "play" button is not swapped to "pause" button. I cannot stop playing
• After ~30 seconds freeze the time jumps to 0:30 and spotify gets usable again

spotify --debug-level=MAX does not provide anything useful additional informations. I get only the two lines on start:

Neither gnome-integration-spotify nor spotify-tray are installed.
Launching spotify without systray integration.

contradicting this message I get spotify tray icon...

I disabled the notifications in wf-panel and started dunst

• The notification appears. (Music cover image at the left and Album name + Track name in two lines at the right)
• No freeze
• No change in spotify --debug-level=MAX output

Tried https://github.com/emersion/mako too, it does work too

You are right, the keepassxc issue is not solved yet. After reboot the tray icon is away again...

For what it's worth, there is an option in KeepassXC to display the tray icon or not, which seems to work fine here.

This Issue I solved by autostart1 = sleep 5; keepassxc now.

Seems to be a timing issue in autostart processing.

[NamorNiradnug]

I've found another bug and it should work now (at least I've finally installed spotify and it works for me). Although it looks ugly because notification's text and image are side-by-side and image is large. Probably the best solution is to scale it (gonna fix it soon).

P.S. fixed this thing too, could you please check whether it works for you now?

[bell07]

Confirm the spotify notification does work for me as expected and there is no freeze if #284 is merged
