Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

A plasma crash happened and I had some debuginfo packages missing, so I pressed the button to automatically install them. It didn't find any and asked me to configure the repositories. As I know this wouldn't have helped, I said no. The progress dialog hanged at 75 %, so I closed it and the dialog closed. The 'install debuginfo packages' button did NOT reappear.

After manually installing the packages and reloading the back trace I wanted to report the bug. On clicking the button, DrKonqi crashed. Looking at the backtrace, I suspect it trying to delete the dialog again, but it was already disposed when cancelling it.

Reproducible: Didn't try

Steps to Reproduce:
see above

Actual Results:  
DrKonqi crashes when clicking the Report Bug button

Expected Results:  
It should just go on and not try to delete the progress dialog again if it was already disposed (or even better, not hang in the first place).
