File autolaunch association lost when alacarte move/delete items

[ybaruss]

When sorting out software items with alacarte, the "auto-launch association" of a file is lost.

That is what to do to see the bug:
Install KmPlot package from softwarestore and you'll see it with an icon all correct in Education submenu of Application on panel.
Make a plot and save a ".fkt" file somewhere.
In explorer the "auto-launch association" is not done and if you try to set it you see it is not being proposed even if in alacarte you can see it.
With the explorer tool create a new "auto-launch association" entry with command kmplot for the ".fkt" file you created: you will see that a new entry is proposed in explorer menu but without correct icon and in alacarte there is now a new entry also with no icon in Other sub section.
Now close explorer and in alacarte drag and drop the kmplot "auto-launch association" entry from Other to Education. Because the drag and drop action has copied the entry, delete the one in Other section.
Now open explorer and try to double-click on the ".fkt" file you previously have associated to kmplot : it is lost.

I would expect that:
Explorer "auto-launch association" menu would display software available the same as alacarte.
Also that alacarte would not break "auto-launch association" set with Explorer when sorting them.
