Looks like you both have different problems (or at least the same one but different visible consequences :) and I am a little puzzled since I can't reproduce them. NVu works just fine here.
@Bump: is this a fresh install or an upgrade from a previous version? @Sven: /usr/bin/nvu should use /usr/lib/nvu-1.0/run-mozilla.sh. Do you have MOZILLA_FIVE_HOME defined in your environment variables? ** Changed in: nvu (Ubuntu) Importance: Untriaged => Medium Assignee: (unassigned) => Jérémie Corbier Status: Unconfirmed => Needs Info -- nvu 1.0-0ubuntu4 broken https://launchpad.net/bugs/51846 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
