Well, just extend your .gitignore?

Patches, relicts of merge conflicts and others should all be ignored Git.
The file in KDevelop looks pretty naked indeed :)

Also, try pay more attention to the bottom part of the editor window (which 
lists untracked files) that pops up when doing a "git commit".

Works (relatively) fine for me.
