Please describe the problem:
When you click on a file, and choose Open With, you get a list of different applications proposed. If you choose now "Open With Other application" and you choose an application that was not in the first list, this application will be set as the default mime type handler (e.g. choose Epiphany in Open With Other Application for a JPEG file).

When now opening the same dialog "Open With Other Application", but choosing an application which was already in the proposed list, this application will *not* be set as the default mime type handler. This is in contrary to what the text in this dialog is saying: "Open foo.jpeg and other files of type "JPEG image with", which implies that it will become the default handler.

This inconsistency is very confusing, as I firstly thought it was a real programming bug (http://qa.mandriva.com/show_bug.cgi?id=29641).

The best way to solve this in an intuitive way, is to never set the mime type when Open With or Open With Other application is chosen, but only when the Properties dialog for the file is used.

Steps to reproduce:
1. Right click on JPEG image, choose Open With Other Application, and choose Epiphany
2. Notice that from now on, all JPEG images are opened in Epiphany
3. Right click on JPEG image, choose Open With Other Application, and choose Image Viewer (eog)


Actual results:
When choosing Open With Other Application - Image Viewer, the file is indeed opened with eog. When double clicking another time on the same file, the file is again opened in Epiphany. This behaviour is not consistent with point 1 and 2, and not consistent with the text in the dialog

Expected results:
According to the dialog, all JPEG files should be opened by default with Image Viewer from now on.

Does this happen every time?
Yes

Other information:
Maybe the best solution to solve this in an intuitive way, is to never set the mime type when Open With or Open With Other application is chosen, but only when the Properties dialog for the file is used. Of course, then the text in the dialog has to be modified.
