clearlooks is the name of a gnome theme, and so you wouldn't have it on
your kde machine.  You can ignore that and other gtk "warnings".

Now that one looks suspicious. The only idea that comes to mind is that
gtkam for some reason is trying to save to some place you don't have
write privileges, like / or /run, maybe.  That's where I would trot out
strace, which will allow you to see exactly where gtkam is trying to
write when it fails.

The other trick I use is to create a new user with a new home directory
and try running gtkam from that account.  Often I find that the new user
doesn't see the same bug as my normal user, so at least I know the problem
is somewhere in my home directory, and strace will narrow the scope of
my debugging even more.

The "-y" and "-e file" flags for strace are very handy for this kind of
debugging problem.
