I just backported the qxembed changes to KDE_3_1_4_RELEASE,
recompiled libkdeui, replaced libkdeui.so.4.1.0 in my system,
and restarted kde...

Everything seems to work fine.
- web page with multiple flash plugins...
- web page with java applets...
- panel applications...

Time to make a commit in the main branch.
With a meaningful log message of course ;-).
