Bug 20735

When I try to open a non-executable shell script (including ruby and python scripts) from Nautilus, Nautilus asks Wine to open it.

Expected behavior:
A text editor should open the script file.

Originally reported here: https://bugs.launchpad.net/ubuntu/+source/wine/+bug/192122/ and was told to report it on bugs.freedesktop.org. So since I couldn't find the bug in the database here already, I'm reporting it.

Ok, I can now confirm this and I believe I know the source of the issue. The problem occurs with shell scripts, python scripts, ruby scripts, and possibly others.

Basically, Wine is (correctly) associated with MIME type "Application/x-executable", since this covers some .exe files (including non-Windows ones generated by Winelib). shared-mime-info classifies shell, python, and ruby scripts as sub-classes of application/x-executable, so anything that can open x-executables is used to open the scripts (in this case Wine). Since "sub-type of executable" is listed before "sub-type of text file" for scripts, handlers for executables (Wine) show up before handlers for text files, and thus Wine gets used to open it.

One possible fix is to get rid of the sub-typing in shared-mime-info. It's unlikely anything that could open "executables" should also be opening python/ruby scripts in this way (in fact Wine is probably the only program associated with executables at all). Another possible workaround is to just switch text/application so that the default becomes the text editor handler, but this leaves the problem with Wine still being listed as a handler for something it isn't.
