Affects: gdm (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
gdm 2.13.0.8-0ubuntu1on dapper:
At the gdmgreeter login window, if I click on the text "Username", it crashes and gdm is restarted.

There is nothing special in /var/log/gdm/\:0.log*, enabling Debug in
gdm.conf (and restarting) doesn't help.

strace:
gettimeofday({1140354437, 595205}, NULL) = 0
poll([{fd=3, events=POLLIN, revents=POLLIN}, {fd=0, events=POLLIN|POLLPRI}, {fd=5, events=POLLIN}], 3, 202) = 1
ioctl(3, FIONREAD, [64])                = 0
read(3, "\5\1\330\3\377\321k\202C\0\0\0004\0@\0\0\0\0\0\312\1\271"..., 64) = 64
gettimeofday({1140354437, 632594}, NULL) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---


I'll attach gdb output.
