I
think I had the same problem, first about a week ago, and again about ten minutes ago. Thunderbird would not launch after I restarted X for some reason. I don't know what caused it, and truthfully, I have no idea how I fixed it initially because I was trying to fix something else.
This time, however, I used the shell and ran:
Code:
mozilla-thunderbird -verbose
.
To my surprise, it launched. I have no idea why. None whatsoever.
Running debian unstable, mozilla-thunderbird version 0.7.3 (20040818)
