+
+Some packages do not get installed from Core Release (or dvd), during upgrade,
+as they are required by packages that are in Mandriva, but not in Mageia 1.
+(Requires with explicit versions).
+
+When that missing package gets added to updates, mgaapplet will also try
+to install the dependencies from Core Release, to get the right version.
+
+Likewise with the dependencies of those dependencies.
+
+In the original bug 2097 (the one that triggered the filing of bug 2317),
+kipi-plugins-expoblending could not be installed due to hugin only being
+in core release.  So hugin was added to Core Updates.
+
+The update still failed, as hugin requires enblend, which was only in Core
+Release.  So not only do we need to link added dependencies, but a
+recursive list of dependencies, with no easy way to figure out which
+ones are really required.

+
+Yes my attempted patch failed.  In my opinion, what we need, is for mgaapplet
+to use it's current method to determine if there are updates, but use the
+equivalent of urpmi --auto-select, to actually get the updates list, and
+install them.
