Comment 1 Thomas Friedrichsmeier 2011-11-03 07:59:25 UTC

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

Thank you Thomas.
