Bug 346740

Thank you so much!

We have 2 bug reports with this exact trace but the reporters no idea how they managed to make it happen; they were just clicking on some entries, which never crashed for me. This did.

Being able to reliably reproduce a bug makes it soo much easier.

*** Bug 345859 has been marked as a duplicate of this bug. ***

My trace inline as it has some symbols missing previously

I'm glad that I could help :D

some extra debug for me.

0x8abd880 "transitionStarted()"
0x8abeda0 "transitionEnded()"
0x8abd880 executing a script
0x8abeda0 executing a script

it crashes in that second execute script; "transitionEnded"

This comes from the PageStack

It's acting like it's had the JS context removed from under it, but the context should be the systray not the item in the system tray...

I think I hit this one too. F22 updated today, I opened the new telepathy icon on systray, searched for a contact and double clicked on it to open a dialog. Then plasmashell crashed with a backtrace that seems very similar to me (though yeah -ETOOMANYTHREADS to me).
Tried it again, and it didn't happen anymore..
FWIW plasma-workspace-5.3.0-3.fc22.x86_64

*** Bug 348230 has been marked as a duplicate of this bug. ***

I just experienced a crash and based on the stack trace it appears related. I'm including it below:

Application: Plasma (plasmashell), signal: Segmentation fault

Today I've seen this bug for the first time, happened when I was randomly and fast clicking different icons in notification area, which popped up some info windows (usb devices, media player applet, ...)

Can it be related to desktop effect about closing window (Fade enabled)?

I just hit this  (at least dr Konqui says so)  , also by fast clicking in the system tray.
First happened by fast switch between klipper and telepathy contact list.
I reproduced it by fast switching between telepathy contact list and klipper (that worked). Crash occured when I hit the bluetooth icon.

What I think is important is that in the first crash klipper had never been shown before in this session (and system boot), the same goes for the bluetooth widget (hadn't been shown before).

does this still happen in Plasma 5.7?

I didn't realized it on plasma 5.6.5 if this helps...

still to pay attention to this, but as shortcuts in systray work a bit different in Plasma 5.7, *should* be fixed

I think the problem isn't the system tray per se but the Animator that animates the applets which crashes in some rare circumstances when the window opens and it directly animates or something like that. Might be less likely with the new code which tries harder not to animate whilst opening?

This is extra broken in 5.7. System tray icons are broken and a bunch of icons that are also in the application dashboard. Ones that I have broken are Clementine, Private Internet Access application (downloaded straight from them), I made a custom launcher for Xonotic and it's a .svg file that's broken, KRDC, bmon, SSH AskPass, and xfburn. I hope that's useful information. These icons have been broken for 5.7.0 to 5.7.3

I forgot to add that there's no weird behaviors, just broken images.

That's completely unrelated. Your distribution has (probably) switched to Qt5.7 and hasn't recompiled their KIconThemes package. Please tell then to do that.

We don't seem to have any duplicates >= Qt 5.6.0

At which point we can close this as upstream, if you still see this bug with a Qt 5.6 or later, please reopen this.

this happened to me when i was using latest version of plasma 5.8 with qt 5.6.1 on openSuse leap 42.2
