Jeff,
the new lyx-qt 1.4.2 in unstable is still showing the crash on my
MacBook Pro. I re-read my initial email and noticed that I was
inaccurate in describing how to reproduce the crash. When I said
"erase the math inset and save again," I meant you have to cut the
math inset by using the "cut" function from the Edit menu (i.e., it
goes into the "clipboard") - not just erase by using backspace or
delete-forward.
When I go through the editing steps described above, here is the crash:
lyx: SIGSEGV signal caught
Sorry, you have found a bug in LyX. Please read the bug-reporting
instructions in Help->Introduction and send us a bug report, if
necessary. Thanks !
Bye.

One more little thing - the fink.info removes the O2 optimization for
src/tex2lyx, but I tried compiling the whole source with O2 and had
no apparent problems. I tried importing some tex in my version and it
worked as expected.
