            Bug ID: 309351
          Severity: crash
           Version: unspecified
          Priority: NOR

           Summary: JuK crashes when one clicks on the "Previous" icon
                    during the first track on the first album on the list
    Classification: Unclassified
                OS: Linux
          Reporter: wolf.halton@gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: juk

Application: juk (3.8)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.2.0-26-generic-pae i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I hit the dropdown to go back one during the first track on the first album in
the list.
What I had expected was a graceful refusal, I guess. i.e. "This is the first
track, you cannot back up further.  Have a nice day."  Or maybe it would go to
the last track on the last album.
Crashed the JuK app immediately.  Tried it a few times to make sure that was
its behaviour.
The dropdown is not labeled and the tooltip when hovering a mouse over it
doesn't suggest it has the power to crash JuK.

The crash can be reproduced every time.

-- Backtrace:
Application: JuK (juk), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
