Can't upgrade gtk3 as part of a "upgrade outdated", Segmentation fault?

[ftp83plus]

Hello there, 

just encountered this issue when gtk3 tried to rebuild as part of an upgrade outdated operation:
Relevant extract of main.log: http://pastebin.com/KL0kKinG

Knowing that a Segmentation fault doesn't mean much, I cleaned gtk3 at attempted a rebuild, but it still segfaults for some reason.

What is the source of the problem?
