gnucash-2.0.5-3.fc7, which I installed on March 22, requires
libgtkhtml-3.8.so.15.    gtkhtml3-3.14.1-1.fc7, which pup installed on April 11,
contains a later version of that library.  Hence, after updating with pup,
gnucash no longer works.  pup should not have installed a package which broke a
dependency for an existing package.  Rpm gets this right, i.e., if you try to
use rpm to install an update for a package which removes a dependency of another
package, rpm will refuse to do it without --nodeps.

I'm marking this a high-priority defect because I don't think it's at all
acceptable for pup to be able to break installed applications.
