A quick grep of the sources indicates a significant number of these corrections are needed. I'll start pecking at them.

To be sure I'm not making a mess, both of the following types of lines should be changed to TQString?

<signal>***(const QString&amp;)</signal>
<slot>***(const QString&amp;)</slot>

I tested tdebase by rebuilding with a patch and the xsession error disappeared. The patch did not resolve the What's This bug, but KControl functioned without incident.
