That sounds a lot like what happens with NFS /home mounts when the 
directory dies after login. Users can still mount/refresh their /home 
partitions and login thanks to Kerberos, but can't pull uid/gid 
information from the directory so everything is owned by nfsnobody. This 
has the effect of halting most new program execution because needed 
dotfiles and user-specific temp space can't be accessed, but existing 
processes just start getting weird slowly instead of dying right away.

No idea if your problem is actually permissions related, but it sure 
sounds similar, particularly the kio_file loading error and inability 
for Konqueror or Dolphin to show you contents of directories.
