Bug#733974: Partial diagnosis.

[mbekkema97 .]

I discovered that adding the line:
      return valueToString( value_.int_ );

underneath line 668 of
jsoncpp-src-0.6.0-rc2/src/lib_json/json_value.cpp of the debian
libjsoncpp source package fixes server list, but modstore only loads
titles and gives these errors on the console:
