Ah but the problem is much more insideous than that! This wmaker-conf was
from slink, it was never linked against any of these new libraries. The
problem lies in the library interdependencies.
libgdk-imlib1 in slink did not seem to depend on any glib, in potato it
depends on a new and incompatible glib from potato BUT the soname was not
changed. So the instant you install this new libgdk-imlib1 ~40 apps from
slink silently stop working!

Lintian will not help this, the damage has already be done - the best you
can do is change gdk-imlib1 to gdk-imlib1.1 and recompile all your new
packages and be vigilant to never do this again.
Oh, the other alternative would be to make gdk-imlib1 in potato conflict
with the old gdk that it used to use. That might solve this particular
instance.
