           Summary: Occasional crash in find_basename_module during ie7
                    install
           Product: Wine
           Version: 1.6

        OS/Version: Linux
            Status: NEW

While testing whether bug 21947 was fixed in wine-1.6,
I ran the ie7 installer in clean wineprefixes several times 
(without WINEDEBUG=warn+heap).  The first or second time, it
crashed in update.exe in find_basename_module:

Unhandled exception: page fault on read access to 0x0000002f in 32-bit code
(0x7bc4ea18).

I reran several times, but didn't see this one again.
