Wasn't this discussed on IRC this morning?

fish_execute does not set up X forwarding. So $DISPLAY is empty.

PlasmaPkg is a KApplication
KApplication connects to a display. If it can't find one it just dies.

To test run

"DISPLAY=FOO plasmapkg"
will fail

"DISPLAY=FOO ls"
will work.

you /could/ try and set $DISPLAY to :0 which will probably be the
display of the host the other side.. or as I'm sure I read, change
plasmapkg to QCoreApplication which doesn't have this.
