Unfortunately, today's (nightly) build broke my nightly install on 10.04 x86_64. I filed a bug (my first 'automatic' bug submission on LP), but it seemed to have gone to the main Firefox LP instead.
Anyway, here's what I got when I tried to perform the following steps (after the failed nightly update from the PPA):
sudo apt-get remove firefox-trunk (successfully done)
sudo apt-get install firefox-trunk
