Synaptic needs a small patch to work with the new progress interface in 
latest apt-rpm devel releases. Kynaptic almost certainly has the same icky 
hacks as Synaptic does, this patch should help:
http://apt-rpm.org/patches/synaptic-0.57.2-progressapi-hack.patch

API users aren't supposed to require modifications for the new progress 
stuff, but Synaptic does dirty things to get access to packagemanager 
internals, at which point all bets are of course off. From 
[ks]ynaptic/common/rpackagemanager.h:

#define protected public
#include <apt-pkg/packagemanager.h>
#undef protected
