I’ve been facing a similar issue. For me the problem was that the encoding of the file had changed since it was last opened with Gedit (from WINDOWS-1252 to UTF-8). As I had manually set the encoding when first opening the file, Gedit had saved this information and tried to reuse it the next time I opened the file after the encoding change; this resulted in said error message.
To fix the problem, I had to remove the saved encoding information from the gvfs metadata like so: gvfs-set-attribute --type unset MY_FILE.txt 'metadata::gedit- encoding' I have posted more information on this at <http://askubuntu.com/a/279820/137449>. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067915 Title: gedit can't open a txt file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gedit/+bug/1067915/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
