Yup, we didn't test on Solaris.

However, this is a Gtk+ version problem. The above mentioned function  
does not exist in Gtk+ 2.14 because it would be equivalent to  
G_TYPE_OBJECT. I've fixed this in the darcs repository.

This bug occurs if you're running in anything else but UTF-8 locale.  
As Andy said, this is fixed in darcs.

For the next point, it would really help us, if you could check out  
the darcs repo and build again. That would then also entail ironing  
out the problems with Gtk+ 2.14.

This would be very interesting to resolve.

I assume:

- you use -threaded to compile your program
- you only use postGUISync and postGUIAsync from threads different to  
the Gtk2Hs thread

Is this true? If yes, I'll give you an elaboration on how threads are  
supposed to work in Gtk+ (I think I finally understood this!) and what  
I've changed in 0.11.0.

Cheers,
Axel
