I don't know if you can draw any good conclusions from that on a linux install.
Seems just as likely that after your 64 bit install switch, 32 bit libraries it was depending on were missing.
Linux distros don't tend to be as obsessive at maintaining full 32 bit support as the Windows world.
A better test would be to fire up a 32 bit VM and see if Firefox 32 bit crashed there...
