Comment 2 for bug 1033577

This isn't a wine issue. It's a subdirectory thing. It seems that if you put a .desktop file > 1 subdirectory down, it won't work. I tested this with chromium.desktop.

Placing it in ~/.local/share/applications/test/ creates an entry in gsettings "test-chromium.desktop" and it persists when I log out/in.

Placing it in ~/.local/share/applications/test/test2/ creates an entry in gsettings "test-test2-chomrium.desktop" and it no longer persists.

If I make the entry with "/" instead of "-" it persists no matter what.
