k3b can't write inf files


I found this list as the maintainer contact for the k3b software. Thanks
for the hard work you put in, it's a great CD writer!

I use k3b on Linux Mint and my problem is that it tries to write some stuff
in the /tmp/kde-$USER folder but the folder is not present. Instead there
is a /tmp/kde-$USERsomeothercharacters folder. So CD writing breaks with
an IO error message unless I make a symlink.

I wonder if this is some incompatibility between software I have or
something intrinsic to k3b. Or maybe user error.

Anyway, here is my uname and some (hopefully) relevant installed packages:
