Description David Kelly 2006-11-09 02:58:43 UTC 
Steps to reproduce:
1.  Did a "portupgrade -auy" in FreeBSD 6.2-PRERELEASE while pan 0.118 was running. A lot of KDE and GTK stuff was updated.
2.  System crashed with pan still downloading about an hour after I walked away. Have no idea what the system crash was all about.
3.  Pan now instantly core dumps on attempt to restart.
4.  Thinking libraries or something changed in the portupgrade (am not using pan from the FreeBSD port) I returned to the 0.118 sources, "make clean ; ./configure ; make install". Same result. Stack trace below:

Murphy's Law just bit. rm'ing the file mentioned above allowed pan to restart and resume for long enough to click the Submit button. New core dump, same error message, much different backtrace:
