there seem to be a number of different problems reported here, some of which may be fixed in current trees.
Given where f14 is in its lifecycle, it's unlikely to see further fixes beyond security bugs, and easily backported identified changes.
If you are still having problems on f15/f16beta, please file a new bug against the relevant release. Tracking them independently is the only way to really get a handle on this.
