Sebastioan,
a uninstalled all from GNUstep, copied and reinstalled from svn as you said, and also ProjectCenter, Gorm and GWorkspace.
ProjectCenter and Gorm are fine, even the tooltips appeared.
GWorkspace still has problems. I see its icon appear, but then I get:
[edwin@ridcule tmp]$ openapp GWorkspace
