FireStarter Crash

[Symbolis]

Have FireStarter installed on my Kubuntu box. It works fine(as near as I can tell) for a few seconds, but then crashes.

Missed the error the first time, but re-installed and ran it(via kdesu) from the shell and got this:

***MEMORY-ERROR***: firestarter[7502]: GSlice: assertion failed: sinfo->n_allocated > 0

Any ideas? Package I'm missing?
