Thank you both,

I tried several alternatives and finally kept eog (Eye of Gnome). It
requires only 4 additional packages to meet it's dependencies.

Just as Ludovic pointed out, switching to elogind solves the problem. But,
the amount of packages to install in order to use just one KDE app is
humongous:

root@vaio:/home/emi# apt-get install -s elogind gwenview

The following packages were automatically installed and are no longer
required:

So, I think I'll keep eog until I find something better.

Thanks again.

Cheers,
Emiliano.
