Ehh. I have a newly installed Mint 12 box with gnome 3.
I have that annoying thing, that when I click a text .pdb files, it opens with gedit.
Then I can right click and select .pdb files to open with pymol.
But when I then click a .txt file, it opens it with pymol.
I know its something with mimetypes, and I got it to work on my mint 11.
But now I am a little lost, and can't find it on the web...
So, anyone did this?
