Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.6-201.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

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

The crash occured sometime during the night when the computer was not actively used. This has also happend a few times in the past, including during active use.

Maybe this is related to crappy video driver performance. Vlc frequently complains about things, like

[h264 @ 0x7f0afcf3ee80] hardware accelerator failed to decode picture                                                                                                                                    

and sometimes fail to display (just black screen, audio ok) a second/subsequent video in a playlist. Stopping video playback and starting again helps.
