Isaac,

Unfortunately that is where the backtrace ends. It seg
faulted last night while sitting at the list not being
used by anyone. I did a backtrace this morning which
follows and as you can see it ends at the exact same
place that the last one did. Although this one
mentions having trouble with mysql.
