Gestan installer backtrace

While trying to test bug 21978 with wine-1.1.44-170-g69326aa, I noticed that
trying to launch the Gestan installer induces a crash within an xrender helper
in winex11.drv. This only seems to happen when running the installer within an
NX session; running within a local X session doesn't seem to cause a crash. The
relevant backtrace is attached.
