Using ssh *should not* make much of a difference, certainly not a
complete failure to display like you are reporting.

Is there anything in the xpra server log at all?

This error comes from the Qt application itself.
Why it would encounter this sort of problems when xpra is its window
manager, I have absolutely no idea!
But there were some qt/kde theming fixes in the past few months and I am
running Fedora 16 here (which has them) whereas Fedora 15 may not have
them (yet)..

I am installing the full KDE on a Fedora 15 virtual machine to test.

PS: emacs 24 from source also works fine.
