Privacy issue #2622
From the projects website 
libgdata is a GLib-based library for accessing online service APIs using the GData protocol — most notably, Google's services. It provides APIs to access the common Google services, and has full asynchronous support.
libgadata is in
your-privacy-blacklist.txt (formerly known as
your-coherance-blacklist.txt) since commit 8d91f458f9cf466b20438d45454b90281345230e .
The mentioned reason in the package:
provides support for unsafe and dangerous for privacy services
I tried to find some security issues related to it, but the ones I found (such as ) were closed before libgdata was blacklisted.
I looked also at parabola's mailing list at that time, but could not find more informations.
Probably the reason for blacklisting it is the google dependency. I think this could be a good moment to re-evaluate libgdata and (at least) clearly state why it is blacklisted.
Packages that depend on libgdata and are blacklisted today:
|Package||Replacement in [nonprism]||Notes|
|gnome-online-miners||provides support for Facebook, Flickr, Google and SkyDrive|
|shotwell||contains support for Facebook, Flickr, Picasa, Tumblr, Yandex and Youtube (Note: Youtube option has support for registered users only)|
