first of all, the forums are not the place to report bugs, if you're too lazy to make an account on bugzilla, you can find me on freenode or pm me with the details (preferably the former).
second of all, this isn't a bug. it's caused by the fact that no gpp compatible ui.qvm is in the search path, and that won't be an issue when the released version has its ui.qvm in base.
