Does setting MONO_DEBUG=explicit-null-checks change the behavior? If so, that's bug 32302.
If not, please get a log with WINE_MONO_VERBOSE=1 WINE_MONO_TRACE=x and a backtrace from the same attempt that produced that log. (You'll need Wine 1.5.25 for the WINE_MONO_VERBOSE variable to work.)
How can I do that?
