Description of problem:

GConf uses the directory /tmp/gconfd-$LOGNAME for storing a lock file (and
possibly some other stuff -- I do not know, I know nearly nothing about GConf)
even if GCONF_GLOBAL_LOCKS environment is not set. As the /tmp directory is
sticky, it is possible for any user to create the directory with this name prior
to first login of a new user, effectively preventing it from using GConf
clients. The impact of this is quite serious, as the user can't use most of
Gnome, Evolution, etc. and it's quite hard for a non-technican user to work it
around.

Additionaly, I think any temporary directory and file should disappear when
application terminates. It is obvious that it is not a good practice not to do so.

Version-Release number of selected component (if applicable):

At least FC5 and FC6's GConf.

How reproducible:

Before user logs in/launches GConfd for the first time. Some systems erase /tmp
at each startup or use memory-based filesystem for it. In that case the problem
is reproducible after each startup.

Steps to Reproduce:

This migh be obvious enough
while (true); do touch /tmp/gconfd-$(tail -n1 /etc/passwd |awk -F: '{print
$1}'); done
