Unfortunately, the backtrace is not useful. If you can reproduce this bug, please read the following page and paste a better one: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports Giving steps to reproduce the bug is also needed.
Looks related to bug 185468 which should be fixed on Qt4.5.1+. Thanks
Dario: you've gotten very good at identifying duplicates; you should just close the ones with backtraces that are this close to each other :) *** This bug has been marked as a duplicate of bug 185468 ***
