I am 80% sure that this is a separate problem.
(Yes: I wasn't careful enough in saying this. Accelerator keys have not
appeared in menus in recent versions of 1.5.x.)

Abdel, I think this means that QAction cannot be subclassed safely in
Qt/Mac: the code there copies our QLAction objects as if they were
QAction, and the part that contains the FuncRequest gets lost. It
seems to me that your nifty scheme does not work :(
What I read above is that the action triggers, but the QLAction object
is not valid.

I believe that I didn't have this crash with an unpatched version, but
since it's been a while, my memory is fuzzy.

Same here.
Bennett, what happens if you comment out
# define MERGE_MAC_MENUS
in QLPopupMenu.h?
About LyX and Preferences don't show up in the LyX menu (that is, the
Mac default menu that appears on the left).
However, there is a new LyX
menu that appears on the right (after the Help menu), which contains a
single entry: Quit.
I assume this is due to my last patch.
There's also an Exit entry at the bottom of the File
menu. Preferences shows up in the Tools menu at the bottom, and About
LyX shows up in the Help menu at the bottom.
I haven't carefully looked at this. I had to reapply the patch, and it
didn't apply cleanly (though I believe I cleaned it up). But I'm
starting to notice some crashes I haven't noticed before, which may or
may not be a result of this patch. However, I'm really swamped right now
and don't have time to investigate.

Maybe all the problems are related to the moving of menu entries:
