I agree that crashes are a problem.  In Aquamacs, I have recently enabled 
semi-automatic crash reporting (we get an e-mail with the crash log the next 
time the user starts up the app, and chooses to send the report).  I get a lot 
of those - 134 in August, and rising, as people upgrade to the latest version.

These are way more crash reports that I can act on, so they never end up on the 
Emacs bug reporting database.
Out of 300-something reports since June, the last Emacs functions (and Emacs 
versions)  reported are listed below, ordered by number of occurrences (showing 
only those with more than 2 crashes). Some of them are spurious, obviously, 
such as the "Fsignal" ones. (Mind you, the actual crashes often occur in the 
OS, but chances are they're happening because we're doing something wrong.)

The full reports are available publicly:  
http://lists.aquamacs.org/pipermail/aquamacs-bugs/

And by the way, I freely admit that Aquamacs is buggier than the original 
Emacs, but that said, I should think that such statistics may be a starting 
point in prioritizing the work.  x_set_frame_parameters(), ns_findfonts(), 
nsfont_open().
