Looks like another example of bug 4143 or 4604.  Proposed patches are here:
http://bugs.winehq.org/show_bug.cgi?id=4143

Please try them out and see if it fixes the problem.  It will also
help for you to post the test program somewhere so other people can
try and maybe it can be included in the wine test suite.
