Comment 5 for bug 123917

I have the exact same problem, I just installed Gutsy Tribe 2, installed firefox through aptitude, and i get this exact same error when running for the first time.

I could not find any lock-files, i can tell you that even though i cannot start firefox, the profile-manager does appear to create 2 (0-size) files when i try to make a profile. Hope this helps in some way.
