abrowser and firefox-3.0 commands don't work

Binary package hint: firefox-3.0

Choosing abrowser from the applications menu makes it appear in the gnome-panel for a few seconds with "Starting A Web Browser".

The firefox command works fine, but abrowser and firefox-3.0 do not. I have only experienced this problem with the version from asac's ppa.

$ abrowser
exec: 118: /usr/lib/firefox-3.0.2/abrowser: not found
$ firefox-3.0
exec: 118: /usr/lib/firefox-3.0.2/firefox-3.0: not found

$ which abrowser
/usr/bin/abrowser
$ which firefox
/usr/bin/firefox
$ which firefox-3.0
/usr/bin/firefox-3.0

$ ls -l /usr/bin | grep firefox
