dmg 94ea7051f9 GException improvements with multithreading
Read all GError fields in GException constructor and free GError memory.

Quote from gtksharp2 fix: The original impl did not take into account exceptions marshalling across thread boundaries so it could end up with the error being accessed after being disposed.
