Good tip, but I meant: if the bug isn't easily reproducible.

E.g. I had that a few times with the exceptions thrown by xapian at random 
times. KMail crashes, backtrace is useless, and doing the same operation as a 
user doesn't lead to the exception being thrown again, it's rather related to 
some background operation happening at random times.
Sure I could have run kmail in gdb all day, but it only crashed once a month 
or so. Being able to inspect a core dump is a lot simpler.
