Version:            (using KDE 4.1.0)
Installed from:    Mandriva RPMs

For some reason, in Kopete's Account dialog only my single identity was shown, but the two accounts under that identiy were not there anymore. I clicked on the Add Account button to re-add the accounts, and the Kopete crashed with the backtrace beneath. When I restarted Kopete, the accounts were back and Kopete worked as normally.
