I've had that, in the past, when I've not had a "sticky" bit set on
the /tmp permissions.

[tim at suspishus ~]$ ll -Zd /tmp
drwxrwxrwt. root root system_u:object_r:tmp_t:s0       /tmp
[tim at suspishus ~]$ ll -d /tmp/
drwxrwxrwt. 66 root root 4096 2009-09-12 21:28 /tmp/

Switch to another console, e.g. CTRL+ALT+F3, and try logging in again in
the text environment.
