[Mono-devel-list] Segmentation fault in mono_class_from_name

[Torstensson, Patrik]

I had the same problem and that was related to an old system.dll being
in the path, therefore the process failed to load system assembly
correctly (didn't have time to debug why it didn't warn me correctly.).

 Can you check if you have any system.dll in the path and in that case
just temporary removing them to check if that solves the problem.

Maybe this is an issue with system.dll being both in path and GAC.

Ergh, of course if image is NULL, image -> name_case is causing
segfault... 
So how is it possible that system_assembly is NULL here? I assume this
is not 
a valid state, so I need to debug why it is not properly initialized...
