Slight correction:
It's the preview button that lead to a crash.

After fresh start it seems safe, but once I scanned something and click "Preview" it's Guru-time.

No plugins installed, but "SCANdal" and "SCANdal.readme" get listed (again some sanity-checks might be in order here), none of them selected offcourse.

Overall I must say the scan-results are less than satisfying, colors are way off, might try if "Curves.plugin" gets better results.

AFAIR the last time I had it running (under OSX) it was also dome with SANE-based drivers, so better results should be possible.
