I had exactly the same problem. My solution was to check the alphanumeric foldername (xxxxxxxx.default) in the /home/username /.mozilla-thunderbird folder. I discovered I had appended the word "NEW" to the 8 character.default name during a file transfer from another computer. Once I removed "NEW" from the folder name, all returned to normal.
