Bug ID: 370650
           Summary: Crash on session restore
           Product: kmix
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general

Application: kmix (4.6)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.1.31-30-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

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

I have kmix running all the time. In the past this meant that it would get
automatically started as part of the session restore. However, since a few
months, kmix won't restore for some reason. Today I noticed an icon that
indicated that kmix had crashed. I think it may also have crashed those other
times it didn't start, but either I didn't notice or crash reporting for system
tray apps didn't exist or work back then.

I didn't interact with kmix in any way during the session restore. For example,
I didn't press any media keys like volume +/- on my keyboard.

The crash can be reproduced every time.

-- Backtrace:
Application: KMix (kmix), signal: Aborted
