ODBCManageDataSourcesQ4 crashed with SIGSEGV in QAbstractItemModelPrivate::removePersistentIndexData()

I deleted a User DSN and then closed the Window using the OK button at the bottom. After that, apport popped up, but I didn't experience any other unexpected behavior. I also haven't been able to reproduce this crash.
