Comment:
Well, I tried adding 15 users and I still couldn't reproduce the freeze.
However, I got a nastier problem instead!

After adding all fifteen and clicking 'OK', the app seemed to be doing
something for a few seconds, then quit (no crash report etc). So I took
a look at /etc/passwd and none of the new users were listed. Directories
had been created for them in /home though.

I then found out that I couldn't use sudo (root), because of some
authentication error. On typing sudo <commandname>, it would prompt me
for my password and then fail to execute the command, silently. I
couldn't use slocate either because 'the slocate group does not exist'.
With my root access gone, I had to reinstall Dapper off CD.

Tricky one!
