I would suggest to  set up a test:
# strace -s 256 -f -o /tmp/somefile -p <PID_OF_GETTY_ON_CONSOLE>"

If you are running nscd, suggest to "strace" this as well.

Then repeat your login test, and search the tracefile(s) for signal 13, 
identify which process held the other end of the pipe, and why it went 
away - most likely some subprocess died/segfaulted without leaving other 
traces in the logs.

Hope this helps
