Following kontact (or kmines, or whatever else) crash on exit, drkonqi itself crashes, which then triggers it in a seemingly infinite loop.  I'd be less than surprised if there's a common root cause, but that's for investigation.  Anyway...

Application: drkonqi (drkonqi), signal: Segmentation fault

Reproducible: Always

Steps to Reproduce:
1. Start kontact, or some other application that (currently) crashes on exit
2. Exit said app

Actual Results:  
Get a message from drkonqi that it crashed

Expected Results:  
drkonqi should have done something useful
