Different system. I'm seeing this message in my xsession log. The message occurs after I see messages about autostart apps and in the messages where kcompmgr seems to be starting. Messages immediately following:

No composite extension
trying '/root/.xcompmgrrc' as configfile
finished parsing the config file

Which probably indicates the error is associated with kcompmgr.

The message itself is from tqt3 qlayout.cpp:1227:

qWarning( "TQLayout: Adding %s/%s (child of %s/%s) to layout for "

Any ideas how to resolve?
