Bug 172225

Version:            (using KDE 4.1.2)
OS:                Linux
Installed from:    Ubuntu Packages

Launch Konqueror twice, from krunner, so as to get to new windows. Then close them with ctrl+Q, in any order. You will get a crash.

You may find other variants that lead to the same crash. Like launching one Konqueror and getting the second window with ctrl+N.

Below are the backtraces:
Application: Konqueror (konqueror), signal SIGABRT
