[Mono-list] Gdk.Pixbuf error in Mono

[Bryan Buchanan]

Hi,

Futher to a previous message I sent to the list, I downloaded the latest
GTK source:

glib-2.8.6
atk-1.10.3
gtk+-2.8.20
pango-1.10.4

and the latest Mono,

mono-1.1.17.1_2

A simple test program and output follows. I've tried all the
combinations of stuff I can, and always get the same error. This is only
on an OpenSuse 10.1 system. On an Ubuntu 6.06  it works fine. As far as
I can see, the library versions seem pretty similar on both.

Any help appreciated !

Bryan
