Application that crashed: kbuildsycoca4
Version of the application: 1.1
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Every time I start Amarok from gnome I get this crash, twice. I fixed it before by deleting a certain file in my .kde directory but it keeps coming back so I'm hopeful that someone will fix it.

 -- Backtrace:
Application: KBuildSycoca (kdeinit4), signal: Segmentation fault
