Application: juk (3.9.1)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.9.2-200.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

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

Invoked Juk of SSH X11 forwarding.  Selected several MP3s from the list, clicked play.  First track played fine, but Juk locked up (both UI and playback) after it completed.  Attempted to close window, and crash reporting assistant popped up.

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