Cleaning out the cruft [FC4 upgrade aftermath]

[Don Levey]

In an effort to clean things up and make sure things are working correctly,
I noticed in Synaptic that I had a number of broken packages.  Some I was
able to fix/delete without problem, but there are two for which I have two
entries in the RPM database.  I am trying to get rid of the older packages;
as far as I know I don't need them.  However, here's what happens when I try
to delete via apt-get or rpm:

Here's where I tried to use apt to do it automatically:
[root at dauphin apt]# apt-get --fix-broken install

W: Some errors occurred while running transaction

So I queried the RPM database to see if it was still holding both:
[root at dauphin apt]# rpm -q librsvg2
librsvg2-2.6.4-2
librsvg2-2.9.5-2

So I tried to remove the older:
[root at dauphin apt]# rpm -e librsvg2-2.6.4-2
/var/tmp/rpm-tmp.6046: line 2: gdk-pixbuf-query-loaders: command not found
error: %postun(librsvg2-2.6.4-2.i386) scriptlet failed, exit status 127

And just to see what happens:
[root at dauphin apt]# rpm -e librsvg2
error: "librsvg2" specifies multiple packages

Any thoughts on what to do?  Should I manually edit the RPM database to
remove the offending entry, and then somehow manually delete the package
from disk?  How could I have gotten into this situation anyway?
