Let me know how I can help.  If asked to do a bisect, it would be helpful
if a starting (i.e., "good") commit were suggested so I needn't bisect the
whole history.

On another note, while Stephan is attempting to reproduce the pixmap issue,
it would be good if he could confirm a crash using this MWE. Steps to
reproduce:

   1. Clear out any settings (e.g., ~/Library/Application Support/LyX) that
   would apply to the next step to achieve default behavior.
   2. Make and make install master (I built against e80e7d8478).
   3. Launch LyX, open MWE (MathFont.lyx).  The math should be "previewed".
   4. LyX -> Preferences -> Screen Fonts -> Enable "Use pixmap...", Apply.
   5. Display -> Instant Preview -> No Math, Save -> Crash.

The resulting crash output to the terminal is attached.  Note that
selecting "Apply" in step 5 behaves normally and doesn't produce a crash.
