[Cooker] new moz breaks galeon

[Adam Williamson]

New mozilla breaks Galeon. It doesn't set MOZILLA_FIVE_HOME, which
galeon needs setting. If you export it manually, Galeon also detects it
wasn't built against 1.1 final, and complains. It does run OK, though,
if you bypass the complaint. Is this being worked out?
