Description Grzegorz Oledzki 2006-02-16 16:30:21 UTC
Version:            (using KDE KDE 3.5.1)
Installed from:    Ubuntu Packages
OS:                Linux

Step to reproduce:
1. Load any file with File|Open.
2. Go to Q&A with Go To|Question&Answer.
3. Go back to editing with Go To|Editor.
4. It crashes before (?) showing the editor window.

It shows up the "The KDE crash handler" window with description:
"The application KWordQuiz (kwordquiz) crashed and caused the signal 11 (SIGSEGV)."
