I've tried moving my Thunderbird profile from one C7 box, a standard PC to another C7 box, a DELL server. I did this by rsync'ing ~/.thunderbird.
However, on the new box, Thunderbird only starts if I run it -safe-mode. If I don't run it in safe mode I see the window flash up and instantly close. No errors or notifications appear in the terminal window.,
Anyone got suggestions on what could be wrong, or how I can diagnose it? Google just seems to bring up hits for problems on Windows boxes.
