Odd - I just did the same thing - layer>tranform>arbitrary rotation.
Clicking 'Rotate' applies the rotation both when I use the slider and
use the "handles" to set the angle....

In short, it works on my installation.

I sometimes find it helpful to run GIMP from the command line when I'm
fiddling with it - often it will spew out very helpful info when
something goes wrong...
