Postgres 8.2.4 Segmentation Fault on Mac OS X

I've been having an annoying segmentation fault with the recent install of PostgreSQL on Mac OS X. This happens whenever I quit psql after changing to a different database.

psql(336) malloc: *** error for object 0x1811000: incorrect checksum for freed object - object was probably modified after being freed, break at szone_error to debug
psql(336) malloc: *** set a breakpoint in szone_error to debug
Segmentation fault

Looks like others have run into this as well:

Apparently it has something to do with readline libraries.... not sure exactly what, though. It's not a deal-breaker or anything, just annoying.
