The test hangs when LC_ALL=C is set as ArgumentNullException is thrown

when code in OnUnhandledException calls ToString() on the passed
exception object. This exception is caught within a try {} catch
block in CultureInfo but still results in code in metadata/object.c
outputting a warning and the code blocking.

This works around the issue for now by instantiating the default
CultureInfo object outside of OnUnhandledException but the correct
solution is probably to look at what is going on in object.c
