9.1 RC1 Install Report ThinkPad T520
Turns out this was a permission issue, the desktop files had been set to
644, and changing them to 744 fixed the problem, and probably does for
the menu icons as well. I've fixed it in pbi-manager, so any updated
PBIs will do this automatically now. In addition it fixes icons in KDE
to not complain about if the program is trusted when you first run it also.
