As a temporary workaround, I made a simple patch to initialize "cards" variable if it's NULL.
Created attachment 1565114 [details] source RPM mumble-1.2.19-12.fc30.src.rpm with temporary workaround
Created attachment 1565115 [details] mumble-1.2.19-12.fc30.x86_64.rpm — compiled package for x86_64 with workaround applied
