[John Gehrig]

  Sorry for the delay... I was finally able to get the crashing machine set up again.
  
  Yes, it looks like the descuctor for `job` was called while the KMessageBox was in the process of being painted onscreen (breakpoint in kauthexecutejob.cpp).
  
  I tried making `job` a `QPointer<KAuth::ExecuteJob>` and QSharedPointer with the original qWarning/KMessageBox lines, but that didn't help. I can't say I'm familiar enough with the intricacies of how KDE/Qt handles object allocations and events to explain...
