8.2.1 activity launch failure not recorded

[Mikus Grinbergs]

I had the RoadMap Activity installed on my 800 system.  I just 
updated (via manual 'sugar-install-bundle') to the latest version. 
Now it does not launch.

The fault is likely to be mine - I either goofed the "manual" 
install, or should not have applied the latest-and-greatest to 
8.2.1.  Nevertheless, I expect that when an Activity fails to 
launch, there would be some sort of log made to help the user find 
out what went wrong.  As far as I can tell, __NOTHING__ whatsoever 
got recorded about the launch failure.
