This is about spawning external processes. Could that be gpg from enigmail? Could you try if this also happens with all extensions disabled? gdb's "thread apply all bt full" might give further hints. The nspr code itself didn't change since ages so we ought to find out what triggers it. Sorry about being that vague.
