I now have a workaround for my problem based on your patch. But still the
PixbufDestroyNotify delegate does not get called.
Bit it would be nice to see your patch in a future release of gtk# if it should
solve this problem.

And I have some questions to your patch:
gch = GCHandle.Alloc (this);
data_handle = GCHandle.Alloc (this, GCHandleType.Pinned);

The second line allocates the memory and pins the data, but what does the first
line do then?
And you pin the DestroyHelper object, but not the byte[]. As the byte[] is no
member of the helper wouldn't it be moved/deleted by the GC?

(sry, but I'm quite new to C# ;-)
