Comment 14 for bug 65274

It doesn't look like the same bug to me. This bug is about a crash because the card style or background image specified in ~/.gnome-hearts.cnf doesn't exist. Your crash seems to happen when it tries to add a style to the hashmap. Please check if the two files mentioned in your ~/.gnome-hearts.cnf exist on your system. If they do, this is a new bug. Please refile.

If you want a fresh .cnf, just delete the one in your home directory and rerun hearts. It will create a fresh .cnf for you.
