Application: plasma-desktop (4.11.16)
KDE Platform Version: 4.14.6

Operating System: Linux 3.19.2-201.fc21.i686+PAE i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
login, no other user interaction.

Did not reconfigure anything since previous login. System (Fedora 21) had a larger update recently but was shut down and restarted several times without problems.

After crash dialog plasma  got restarted and works.

Sound is not working since last update - it works in kmixer/audio setup when I hit the front left/right test buttons but nothing else.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
