Yes, it's a problem with SP.  One of the emails is triggering a crash. 
Based on the output it's probably one of the messages in 
X-Spam.Storage.2000.  If that file has X-SpamProbe headers in the 
message you can probably find the right message by looking for the email 
following the one with d21e5e36fcbd7d69d72ab654c593bb6a in the 
X-SpamProbe header.

If you can get SP to crash by scanning just that file or message with 
train-spam then it should be easy to fix this.  Just send me the email 
and I'll take a look at it this weekend.

Also a stack trace would be a big help.  If you could run the program 
under gdb like this:

gdb spamprobe
(gdb) run -c -v auto-train SPAM .X-Spam .X-Spam.Storage* GOOD .Business* 
.Current* .Friends* .Miscellaneous*

Then once the SEGV happens type "where" at the (gdb) prompt.  gdb will 
print a stack trace that should show me where the crash happened.

All the best,
