That's pretty obviously a bug - Graphics.UI.Gtk.Gdk.PixbufData doesn't
fully implement the (M)Array class.
The MArray class changed in ghc-6.8 and we didn't notice until the
gtk2hs release was already out.
Ah. I knew there'd be a reason...
So there are a couple workarounds, either grab the darcs version of the
0.9.12 branch which contains the fix:
http://darcs.haskell.org/gtk2hs-branches/gtk2hs-0.9.12/
Or use the released version with ghc-6.6.x rather than 6.8.x, since 6.6
has the previous different MArray interface.
Or use the unsafe indexing operators which bypass the bounds check which
calls getNumElements.
Eeek! I just recompiled my existing working code with 6.8.1, and sure
enough it's broken. I was assuming that the new code I added was the
problem, but no, apparently it's the change of compiler [and hence
libraries]. Well that changes things...
What do I need to compile the darcs version? Just GHC? Or do I need the
GTK+ header files? (Remember, I'm on Windows here.)
