Version:            (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages

While using Konqueror, accessing the Settings menu revealed a dimmed "Save View Profile".  I then closed Konqueror via the upper-right "X".  Quitting and restarting Konqueror has fixed this error in the past.

After clicking the "X" to quit, a crash occurred with the following backtrace:
