Firefox 3.6 with-plugins was installed and working correctly. I updated some packages on debian:

libc6-i386 (2.7-18lenny2)
libc6-dev (2.7-18lenny2)
libc6-dev-i386 (2.7-18lenny2)
haskell-utils (1.11+b1)
ghc6 (6.8.2dfsg1-1.1)
ghc6-prof (6.8.2dfsg1-1.1)
haddock (0.8-2.1+b1)
(There were more, but these looked most suspicious)

Afterwards firefox segfaults:
/nix/store/chgdrh4cwbx533q9pn13ndk8ng059hbw-firefox-3.6/bin/firefox: symbol lookup error: /usr/lib/libxml2.so.2: undefined symbol: gzopen64

I have also tried installing Firefox 3.5.7 which gives the same error. I also uninstalled both and removed them with nix-collect-garbage -d, and then reinstalled. I still get the same error. I installed and can run other applications without any problem e.g. Inkscape.

I hope this is the correct place to report this, it is probably more of a problem with my system than with nix-pkgs, but any help would be greatly appreciated. Please let me know if there is any further information I can provide.

Thanks,
Cillian
