[Pkg-kde-extras] Bug#435946: KControl closes when kdmtheme is selected and user is not root

[Ivan Zaera Avellon]

Package: kdmtheme
Version: 1.1.2-2
Severity: normal

--- Please enter the report below this line. ---
When kdmtheme module is selected in kcontrol, it closes without any error 
report. I've run an "strace -f" on kcontrol and figured out that the problem 
is that I don't have the file in $HOME/.kde/share/config/kdm/kdmrc, so 
kdmtheme tries to modify /etc/kde3/kdm/kdmrc, which of course, cannot be 
written if you are not root.

If I launch "sudo kcontrol" from a terminal, then everything works fine.

I suggest to create the "$HOME/.kde/share/config/kdm/kdmrc" file or, better 
(as I suppose that when you change kdm theme you are expecting to change it 
for everybody, not just you as it does not have much sense), tell the user 
that he must be an administrator to change KDM's theme.

I send the final lines of the strace below:

access("/home/ivan/.kde/share/config/kdm/kdmrc", R_OK) = -1 ENOENT (No such 
file or directory)
access("/etc/kde3/kdm/kdmrc", R_OK)     = -1 EACCES (Permission denied)
