In Gnome 3.8, when adding a Google account, gnome-control-center segfaults in a shared library belonging to json-c. This occured when using =dev-libs/json-c-0.9-r1.
After upgrading to =dev-libs/json-c-0.11, the segfault stopped and I was able to add a Google account. I didn't test if it worked with =dev-libs/json-c-0.10-r1.

+ -gnome-online-accounts-3.8.1.ebuild, gnome-online-accounts-3.8.2.ebuild:
+ >=dev-libs/json-c-0.10-r1 needed (#470200 by vax456), drop old
The problem is that with no trace, it is hard to say why it went to json-c since the library is not linked by gnome-online-accounts...
# qdepends -Q json-c 2> /dev/null
I quick grep through NEEDED.ELF.2 also does not raise more results which is normal hence I am reopening this bug report as I will drop json-c from g-o-a dependencies with no further proofs of the problem.

+ Drop json-c dep as discussed in #470200 with Gilles, since I can neither
+ reproduce the problem *now* (I was some months ago). Feel free to reopen if
+ you still suffer the problem with latest versions.
