Description dantheelder 2014-11-13 16:54:26 UTC 
Application: plasma-desktop (4.11.12)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.6-2-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I've had plasma-desktop crash while selecting different applications from the taskbar applet but when I relaunch from the cli it continues to crash.  There doesn't seem to be a single trigger, it can crash without any user interaction as well.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".

Reproducible: Sometimes
Comment 1 dantheelder 2014-11-13 16:55:50 UTC 
This crash is likely the same:

Application: plasma-desktop (4.11.12)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.6-2-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I was switching tasks from the task list applet.  I've seen plasma crash other times on my system as well, sometimes without user interaction so I'm not sure the task applet has anything to do with it.  In this particular case at least it re-launched and the desktop appears to still be usable.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 2 boblovgren55 2014-11-15 09:51:46 UTC 
I have the same exact problem on the same operating system. Is anyone going to take a look at this?
Comment 3 boblovgren55 2014-11-15 22:54:38 UTC 
dantheelder@gmail.com are you using btrfs? I noticed this was happening under btrfs, but when I reinstalled the OS and reformatted to ext4, the problem went away.

So there seems to be some issue between this version of KDE and btrfs.
Comment 4 dantheelder 2014-11-15 23:51:41 UTC 
I'm also using btrfs but I unfortunately can't re-test with ext4 to validate that's the problem.  I can definitely test anything you want with btrfs though.

I can confirm the same bug happens on my machine, and there are two more users on OpenSuSE forums reporting the same behaviour. Essentially:

- It is unclear what triggers the crash;
- After crash it is impossible to restart plasma-desktop from terminal because it crashes again (with the same backtrace). Even killing X server and re-logging in does not help, only reboot;
- It happens both with nouveau and Nvidia drivers;
- Installed from scratch, so no possibility from conflicting plasmoids, old configuration etc.
- I'm also using BTFS as rootfs;
- Backtrace always shows the same place:

#6 0x00007fd933e13574 in __strncmp_ssse3 () from /lib64/libc.so.6 
#7 0x00007fd93114405c in KSharedDataCache::find(QString const&, QByteArray*) const () from /usr/lib64/libkdecore.so.5
Comment 6 boblovgren55 2014-11-16 12:09:59 UTC 
I remembered that 13.2 RC1 x64 had no crashes, so it was strange when I started getting repeated crashes with the 13.2 x64 release. The one different element between when I was running 13.2 RC1 and 13.2 final was that on 13.2 final I decided to try the btrfs filesystem. I was sometimes getting crashes over and over again, as frequent as minutes apart. Now that I've reinstalled, wiping out the btrfs parition with ext4, I have gotten zero crashes. I think this is a serious issue as btrfs is the default filesystem on openSUSE 13.2.

The crashes were exacerbated when my system's HD and bus was under a heavier load, such as running rsync doing backups to an external drive. If I did something in KDE like hover over a minimized window on the panel or some other action like highlighting some files on the desktop, it could completely crash plasma-desktop. The crashes were less frequent when disc activity was lower, sometimes none at all. There also were times when plasma-desktop would crash out of the blue, with no input from the mouse or keyboard.

I'm using the xf86-video-ati so considering the aforementioned comments, the video drivers or brand of video cards don't seem like the culprit here.

My two original bug reports are here:
