Please describe the problem:
Despite changing the "Opens with" dialog to point to my text editor of choice, SciTE or some other text editors, gedit opens.

Steps to reproduce:
1. open nautilus and navigate to a folder on a remote samba server
2. right-clicked on a file with application/x-php mime-type (php file)
3. clicked add and browsed for other text editor (I chose SciTE and tried both relative and non-relative paths)
4. selected the radio button for SciTE that showed up in the list and closed the dialog
5. double-clicking any php file continued to launch gedit


Actual results:
Despite changing the program associated with that mime-type, gedit launches and opens that file for editing

Expected results:
the program associated with that mime-type to open the file instead of gedit

Does this happen every time?
Yes, now no matter what, gedit opens the files

Other information:
I believe this was previously working, and an update was pushed out and it broke.
