FWIW, I have just branched the freerdp package from openSUSE:Factory to my own repository at http://download.opensuse.org/repositories/home:/mhnovell:/Rebuilds:/openSUSE_Leap_15.0/standard/, rebuilt the package and dup'ed them. I can no longer force a crash. Perhaps the rc3 package would be a good candidate as an update to Leap 15.0's rc2 package ;)
