problems with upgrading gnome-sessions [Dapper]

[Shelagh Manton]

Did a dapper upgrade yesterday and noticed that gnome-session postinstall
routine returned a 1 on exit. Tried to fix problem through synaptic "fix"
but obviously this did not work. Foolishly thought it could be fixed up
eventually, like so many upgrade problems seem to, but today I am working
in KDE (thank goodness I do have another desktop) because I can't get into
gnome. 

This is the message apt-get install gnome-session gave

Traceback (most recent call last):
  File "/usr/sbin/update-gconf-defaults", line 56, in ?
    fd=open(defaults_dir+'/'+f)
IOError: [Errno 5] Input/output error:
'/usr/share/gconf/defaults/10_gnome-session' 
dpkg: error processing gnome-session (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 gnome-session
E: Sub-process /usr/bin/dpkg returned an error code (1)


Can I do anything about this? Or should I leave it to the packagers?
