gwenview - rt. click -> External Tools (doesn't take)

All, In R14, when you right-click an image and choose External Tools, any association you make (i.e. gimp) does not get added to the list and is not preserved between gwenview sessions. In the change from gimp 2.6 to 2.8, the executable changed names so I need to update the 'External Tools' reference. If I go though the process of rt-click, External Tools -> Other... and choose the new gimp from the menu, "[x] Remember application association for this type of file", then the image is launched in gimp, but when I rt-click the next image, there is nothing in the External Tools for the new gimp. It goes through the normal "Updating System..." dialog as normal, so I would expect to see the new association in qwenview. (maybe not) This problem seems limited to gwenview as I have updated other file types in the file manager and I believe that worked. I can use External Tools -> Configure External Tools and create/edit the associations. So that part works. It's just strange that there seems to be a disconnect with this setting in qwenview. Anybody else try this?
