Comment 6 for bug 117575

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.4) Gecko/20061201 Firefox/2.0.0.4 (Ubuntu-feisty)

If you call firefox through a symlink, e.g. /etc/alternatives/x-www-browser you get the error:

(gutsy_chroot)hjmf@paleo:/$ x-www-browser

run-mozilla.sh: Cannot execute /usr/lib/firefox/x-www-browser-bin.

The link in alternatives is OK:

(gutsy_chroot)hjmf@paleo:/$ ls -l /etc/alternatives/x-www-browser
lrwxrwxrwx 1 root root 16 Jun 11 14:06 /etc/alternatives/x-www-browser -> /usr/bin/firefox

After looking at /usr/bin/firefox script the error seems to be: in the part that deals with symlinks, seems that somebody missed to pass back the resulting "$progbase" variable to the main process.

Possible patch can be:

+++ /usr/bin/firefox 2007-06-13 16:23:40.000000000 +0200
