And before sending that library to KiberGus you could check where does symbolic link /usr/lib/librtcom-call-ui.so.0 points to. For example in my case it pointed to /usr/lib/librtcom-call-ui.so.0.0.0.orig rather than to /usr/lib/librtcom-call-ui.so.0.0.0 After correction those annoying pop-ups successfully dissappeared. But if you have a gun you should think about KiberGus' idea in any cases.
