I have a similar problem (found via
http://ubuntuforums.org/showthread.php?t=965001) with a user on a
Kubuntu system.
I tried updating kdebase-workspace from intrepid-proposed but the
problem still exists.
Background:
1. System was previously Hardy with KDE4 and KDE3.5.10 installed
2. 2 users: one using KDE4, one using KDE3
3. Updated to Intrepid, KDE4 only
4. The user who was KDE4 only can log in ok and run KDE4
5. The user who was KDE3 (now KDE4) only gets the KDM greeter, enters password
and blank screen with a mouse pointer is seen.
6. Restart X (Ctrl-Alt-Backspace) to get back to KDM greeter : goto 5
The KDE3 user does not have sudo privs if that helps (I notice the
permission denied errors? ) Maybe they don't belong to a required group
on the system and cannot read the files required ?
.xsession-errors shows some failures as noted in previous comments and
that forum link:

========================
System is:
Dell XPS 1330
NVIDIA 8600 using nvidia binary via ubuntu repos
KDE 4.1.3
Kubuntu 8.10
I'm probably going to end up deleting this user and recreating their
account.
