OS:                Linux

After installing new widget, closing the "Download New Plasma Widgets" window, the plasma crashed with following stacktrace. (However, I don't know hot to reproduce it.)

Comment 1 chapinjeff 2009-03-03 16:34:34 UTC

I have seen the same behavior.

Comment 2 Aaron J. Seigo 2009-03-03 20:09:37 UTC

this report needs:

* a full backtrace, see: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

* a method to reproduce the crash

* better description of what led up to the crash, such as which button was pressed in the dialog to close it.
