I just tried the senario you describe on suse 11.2 and it works fine,
with a Konqueror session on the remote machine.

I can detach from screen in xterm and kill the xterm, and I
still have a functioning konqueror and can attach/detach to screen
from the separate ssh session.

I don't see any qt_plugin stuff tho' so you culd try some different
kde apps or non kde like firefox, but you probably need to look at
those errors and the deprecated signal stuff too.

Which kde4 are you running ??
