11.04 Alpha 3: conglomerate chokes opening 270k .gpx file

[Mike]

Binary package hint: conglomerate

my laptop locked up during this bug report, so I have no idea if it's going to contain the attached files.
I attempted to open a 270kb .gpx file and my CPUs were pegged for five minutes. It did eventually load, but was unusable and eventually the system froze completely and needed a reboot.
I'm running this on a 6,2 macbook pro with the latest updates of natty narwhal Alpha 3
