Project that demonstrates error

Description of Problem:

If I launch my app with the debugger in MonoDevelop, the following error is
printed out. 

You can comment/uncomment the thread creation in TileRepository.cs:80

The crazy part is this line:

Stack dump:
0.    Running pass 'Combine redundant instructions' on function
'@gleLLVMVecLightFrontTransform4'

If I launch it without the debugger, everything works fine.
