Thunderbird error
 

When I start thunderbird it starts and I can see that I get a new "mail" every start with the subject "failure notice". But then it quickly shuts down and in the terminal I get the error:
What's up?

EDIT:
btw, I haven't done *anything*. I just got home from school and it was still running. Then I went down to do my laundry and when I got up I saw a message from Netscape Agent, or what is was called. So I clicked "next" a couple of times and I can't get thunderbird to start. Although, it does run when I start it as root.

Also, I tried/got this:

Run thunderbird from as root and see what happens.

alright, cd into the thunderbird directory, add it to $PATH and then try it again.

I did run it as root (said it in the previous post) and there are no errors. Everything seems to be working. I get to the "add email-account" place.

I added the path to the executable file and the lib that was missing (they were in the same dir) to PATH and also to /etc/ld.so.conf and ran ldconfig. No thunderbird-bin is working (although not able to connect to any mailserver) but I still get a segmentation fault when trying to start thunderbird (I get segmentation fault just after loading extensions).

I saw that Thunderbird 1.0 is out but same error there. Seems to me like there is something wrong in my profile-file in ~/.thunderbird

But I don't want to lose my mails so I don't want to remove that dir.

Any suggestions?
