Description Hernán Ramírez 2015-07-15 07:20:42 UTC
Application: plasmashell (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 4.0.7-300.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
I was updating Plasma 5 in Fedora 22 KDE and after the process finished, Plasma crashed.

- Unusual behavior I noticed:
Plasma later restarted, the task bar below reappeared and so did the Fedora icon, before there was an "CPU Pipe A FIFO Overrun Intel" that seemed to be associated to FreeDesktop.

Unfortunatelly, i couldn't report it or track it well.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
