The file "lib/kde4/imports/org/kde/dirmodel/libdirmodelplugin.so" is installed by both kde-runtime, as well as plasma-mobile, which might be a problem with certain package managers.
I can confirm the problem. zypper refused do upgrade plasma-mobile today, presumably because of this (sadly it doesn't tell why).
Your problem is probably unrelated, because the issue about the conflict is older. I only noticed it today (not regularly inspecting the full install log).
