cleanup obsolete /etc/gre.d/ files in maintainer scripts (was: firefox: Couldn't load XPCOM)

[Nathan Adams]

Binary package hint: firefox

I just upgraded my system76 pangolin laptop from 8.04 to 8.10 and now firefox-3.0.3 will not launch:

$ firefox
Couldn't load XPCOM.

It appears that xulrunner is not in the path:

$ xpcshell-1.9
xpcshell-1.9: error while loading shared libraries: libmozjs.so: cannot open shared object file: No such file or directory

Adding xulrunner to LD_LIBRARY_PATH allows me to launch firefox-3.0.3 from the shell:

$ find /usr/lib -name "libmozjs.so"
/usr/lib/xulrunner-1.9.0.3/libmozjs.so
/usr/lib/xulrunner-1.9.0.1/libmozjs.so
$ export LD_LIBRARY_PATH=/usr/lib/xulrunner-1.9.0.3
$ firefox

$ lsb_release -rd

$ apt-cache policy firefox

Archiving obsolete /etc/gre.d files solves the problem:

$ ls -l /etc/gre.d/
total 12
-rwxr-xr-x 1 root root 76 2008-07-28 16:56 1.9.0.1.system.conf
-rwxr-xr-x 1 root root 76 2008-09-25 07:24 1.9.0.3.system.conf
-rwxr-xr-x 1 root root 68 2008-06-10 14:03 1.9.system.conf
$ sudo mv /etc/gre.d/1.9.0.1.system.conf /etc/gre.d/1.9.0.1.system.conf.bak
$ sudo mv /etc/gre.d/1.9.system.conf /etc/gre.d/1.9.system.conf.bak

So firefox is apparently selecting the wrong configuration file for xulrunner at runtime.

actually a xulrunner-1.9 bug

I think xulrunner-1.9.1 already does this cleanup ... we should be able to adapt that easily to xulrunner-1.9 package.

xulrunner-1.9 is no longer in a supported desktop release, closing
