In StreamWriter.Dispose(bool disposing), stream.Flush() is called.
Unfortunately, HttpStream is already disposed, so "underlying" is already
null. HttpStream.Flush() simply calls underlying.Flush(), so this should IMO
throw a NullReferenceException. But, even more unfortunately, the virtual
machine crashes with a segmentation violation, in cvm_call.c line 934, since
tempptr is a null pointer.
