Works fine for me... i'd run fsck at startup (hold down cmd-s for single user boot, type fsck -y, run it again and again until it comes up with no errors, then type logout to continue) to try and fix any errors (such as in the address file) that might be causing a crash. If that doesn't help, try erasing your address file (if it doesn't have any important addresses in it). If it does, gee, i dunno. try opening it in pico or something to extract the addresses.
