http://bugs.winehq.org/show_bug.cgi?id=9546

Summary: richedit assertion failure running Dragon Naturally
                    Speaking 7
           Product: Wine
           Version: CVS/GIT
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: wine-richedit
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

A user reports
"in DragonPad, the command "Scratch That" freezes the program and then
crashes it."  
The log contains

string.c:350: ME_ToUnicode: Assertion `psz != ((void *)0)' failed.
err:ntdll:RtlpWaitForCriticalSection section 0x7bc8cd24 "loader.c:
loader_section" wait timed out in thread 001d, blocked by 001f, retrying
(60 sec)

This was with wine-0.9.44-195-g282696b.  
(This is probably not a regression,
but rather a bug uncovered by recent fixes that let DNS 7 work.)
