sigma photo pro 3.5.2 crashes in X11DRV_DIB_DeleteDIBSection.

recipe:

1. install sigma photo pro. (http://www.sigma-dp.com/DP2/spp/setup.exe)
2. prepare a directory with a lot of X3F files.  (300 or so is enough for me)
3. launch sigma photo pro (SIGMA PhotoPro3.exe) and select the directory.
4. push "Save Images As..." button.
5. push "OK" button and wait.

i can provide some sample X3F files if requested.

this might be a regression because i haven't seen
this particular crash with wine 1.1.28.
