OK, this happened to me today for the first time ever with a non-video file, namely by double-clicking on a .tex file, Kile opened twice.
I think that somehow when the system is busy loading the app, the double click event gets sent twice. Or it at least looks like that. So maybe the bug title could be changed to something more generic (if thats possible, don't know if I can do that myself) -- Video player is starting twice when double-clicking on video file https://launchpad.net/bugs/93366 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
