kdesu started to hang a while ago.
Since it just silently hung, I didn't know what was happening.
kdesu never made a password dialog, and it just hung forever.
After a significant amount of search, I was reminded that strace could be useful.
"strace kdesu foobar" hung at the line, connect(9, {sa_family=AF_FILE, path="/tmp/ksocket-$USER/kdesud_:0"...}, XX.

So I googled the line, and I found http://forums.gentoo.org/viewtopic-p-5716721.html?sid=1253a2f9945bd29f678456722ac62c2c.

The solution was to remove the lock file, /tmp/ksocket-$USER/kdesud_:0.

I think kdesu at least has to notify a user of a stale lock so that one can remove it and make kdesu work again.
Or kdesu can be modified never to leave a stale lock.

Since I don't know how to create a stale lock file, I don't know how to reproduce it, but it seems certainly reproducible.

Reproducible: Sometimes
