I also get exactly the same happening on Kubuntu.
Unfortunately, the backtrace provided does not contains enougth information. If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)

Try to run it under valgrind. It may say where the bug is.
