Message:
Hi!

This is a bug in the qt-at-spi package shipped with Ubuntu 11.10. Since we
cannot do anything about it inside RKWard, I'm marking this bug as
"Invalid".

Reportedly, uninstalling qt-at-spi fixes the problem. See this bug
report:
https://bugs.launchpad.net/ubuntu/+source/qt-at-spi/+bug/877358

For reference, here's a link to the bug in KDE's tracker:
https://bugs.kde.org/show_bug.cgi?id=284005

Regards
Thomas
