15.x Regression: Some Profiles (including featured) can't create some objects (wiki pages, tracker ids or fields, ...)

15.x Regression: Profile Voting System can't create the instructions page.
IT works as expected from 12.x to 14.x, but not using trunk (future 15.x)

It may happen with other profiles in the Profiles Wizard: I just havent' tested them yet.

Tested other profile: Collaborative_Community_12x (one of the 4 featured) and it fails to assign the trackerId or tracker fields in the "... Members Homepage", which used to work.

Reproduced in a show.t.o instance linked to this bug report.
See:

The tracker & items were created properly, but not the references to those objects in the Community+Members+HomePage

Something similar with the "Voting System" profile. The page "Voting" is not created in trunk (but everything works as expected up to 14.x).

Fixed in http://sourceforge.net/p/tikiwiki/code/57295

The issue related to profile Collaboration_Community_12x: yes
The issue related to profile Voting_System seems to be different, since it is still present. See more information above.

Voting System issue fixed in http://sourceforge.net/p/tikiwiki/code/57299 (but in the show instance failing to work, still trying to figure out "An error occurred: Invalid address format" error. I know if I start from a new install this will disappear but I don't want to do that.
OK, the Invalid address format error is now solved by http://sourceforge.net/p/tikiwiki/code/57302 (it happens when sender_email is not set and there are plugins to be approved)
