[aspell] aspell dying during check

[Sean 'Shaleh' Perry]

When I am spell checking a SGML doc that is fairly technical (this time it is
PAM docs) aspell eventually dies.  I think this has something to do with my
liberal use of 'Ignore all' to get past things like '/etc/passwd'.

The backtrace from gdb is:

Program received signal SIGSEGV, Segmentation fault.

the myriad of interators here has my brain in loops.  Wish I could debug it
further.  BTW I also posted this to the sourceforge bug tracker, but thought i
might get a response here.
