Yesterday I've released pygcvs 0.1.3 which fixes a small bug with parsing star coordinaates. The bug appeared when the coordinate part of GCVS entry was a string containing only spaces (for example when the star exists under an alternative designation). There are about 150 such stars in GCVS, for example VY Cep, which is actually another name for RR Cep. Starting from pygvs 0.1.3, such empty coordinates are correctly parsed as a pair of None values.
