This was very likely caused by the libgdata 0.13.1-0ubuntu2 upload which added a dependency from libgdata to liboauth-dev (and thus added the libcurl4-nss-dev dependency which conflicts with libetpan-dev's libcurl4-gnutls-dev). Don't look at the changelog for libgdata, cause it got cut off.
Subscribing the developer that uploaded the last libgdata.
