To really get any useful information, you have to go into gdb.  File
name and line number are nice, but you *really* want a stack trace-back.

I'm not a big fan of hacking around in debuggers, but a stack trace-back
seems like a minimal amount of useful information.  For example, I
sometimes have a procedure called Validate(X), which raises an exception
if there's something wrong with X.  I don't just want to know where in
Validate it failed -- I want to know which call to Validate failed.
