Hello Piotr.
I believe that you have found a bug in the xforms GUI library which is
triggered when attempting to rotate grayscale images by 90degree multiples.
If you have the xforms source code, then the crash is fixed by the attached
patch. I have submitted this patch to xforms.
If you cannot patch the xforms source, then the available workarounds are:
1. Rotate the image outside of LyX and load that.
2. Use the Qt frontend ;-)
