Bug has been identified by the KDE developers to be due to the qt accessibility support via qt at-spi integration.

According to the KDE developers, kubuntu is the main/sole user of this technology among major distros shipping KDE, which is why the issue is not reproducible by them who do not have the at-spi integration in their qt libraries.
