Hi Rodrigo,
Hi all,

I was playing with libgda today and also have problems getting a valid
connection returned. I did a bit of debugging, and found what appears to
be the offending (missing) code.

The MYSQL connection structure is not being initialized as mandated by
the mysql API. As a bonus, take a patch! :-)

After that, I was able to successfully connect.

Cheers.
