Comment 2 Emmanuel Pacaud 2004-09-15 19:27:24 UTC

I've just commited a fix that prevents crashing. But does not solve the real issue.

It seems gog_series_is_valid return TRUE even if Y series is undefined, although
Y is GOG_SERIES_REQUIRED.

Comment 3 Emmanuel Pacaud 2004-09-15 20:10:08 UTC

Fixed in CVS.
