I couldn't start yelp as well. In "/etc/gre.d" there were two files: 1.9.2.17.system.conf 2.0.system.conf
The second one was the culprit. Turns out some another application (chmsee) had requested xulrunner 2.0 as a dependency and this resulted in the creation of said file, which happens to block yelp from starting. This solves the problem and it has no adverse effect on chmsee. cd /etc/gre.d sudo mv 2.0.system.conf 2.0.system.conf~ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/568876 Title: Gecko-dependent apps won't start ("Could not find compatible GRE") To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xulrunner-1.9.2/+bug/568876/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
