Oh great, that bug again. So what happens is this: Designer loads kde plugins, 
which due to their dependencies pull in system qt libraries, in this case 
libQt3Support, which are incompatible to the already loaded QtCore we ship 
with QtCreator. 

I'm not exactly satisfied with the possible solutions, those all have 
drawbacks I'd rather avoid. We'll find a workaround for the 1.0 release.

The good news is, that distributation packages shouldn't have this problem at 
all, since then the plugins and qt creator are compiled against the same qt 
version.
