from the bt, you started an app (probably linked to the very same desktop file) what was it? favorites, all apps, most used.. ?

Comment 2 Marco Martin 2016-10-03 13:16:16 UTC

guesstimation from the incomplete bt: appentry.cpp, line 223

Comment 3 Mark 2016-10-04 02:26:29 UTC

After removing the application it still appeared on the menu so I 
started it, expecting it would force a menu update.

How did you delete the file? When i rm a file in /usr/share/applications Kickoff immediately updates the menu and discards the entry. It seems when you're quick enough you can get it to crash when launching the deleted entry.
