I use Ubuntu but I imagine this affects other distros, and maybe it's not a bug in gourmet. But here's the thing:
First, Gourmet version: 0.14.5
Second, after I uninstall software, I want to purge residual files, so I use the terminal and:
sudo aptitude purge `dpkg --get-selections | grep deinstall | awk '{print $1}'`
This has the effect of "uninstalling" Gourmet, for some unknown...
