Yes, I know about the problem, and it has been fixed in git, but not yet
released (see bug #575469).

I have spent the last few weeks working on integrating Libgnomedb's features
which are generic enough into a libgdaui library for which the sources are
part of Libgda (of course their compilation is optional), so Libgnomedb
won't have any new release. The reason for doing this are:
* it's hard to maintain 2 libraries which are so closely tied
* I wanted to have a control center for Libgda, but this was part only of
Libgnomedb
* Same for a simple database structure browser: the one in Libgnomedb is
useless and Mergeant is yet into another set of sources, so I've created a
new one which will be part of Libgda's sources
* Some of Libgnomedb's widgets are not generic enough to be in a generic
library

I plan to publish that work soon, and will make a 4.1.1 release with all
this.

The way DSN are stored in V4 has not changed since V3, so if you copied the
~/.libgda/config file from V3, it should work with V4 as well. You can check
that with:
> gda-sql -l

BTW, make sure you enclosed that DSN definition in the proper tags:
<?xml version="1.0"?>
<libgda-config>
...your DSN here...
</libgda-config>
