Bug 213482

Version:            (using KDE 4.3.2)
OS:                Linux
Installed from:    Debian testing/unstable Packages

My kopete crashes whenever I close a history window.
Looks like the bug was introduced by a recent upgrade of the system, when 'kdepimlibs' and 'kdelibs5' packages were updated from 4.3.1 to 4.3.2.

Here is the backtrace:
Application: Kopete (kopete), signal: Segmentation fault
The current source language is "auto; currently c".
