From: Arnaldo Carvalho de Melo <acme@redhat.com>
Instead of:
no symbols found in /usr/lib/gstreamer-0.10/libgsttypefindfunctions.so (deleted), maybe install a debug package? no symbols found in /usr/lib/gstreamer-0.10/libgstaudioconvert.so (deleted), maybe install a debug package?
We now emit:
/usr/lib/gstreamer-0.10/libgsttypefindfunctions.so was updated, restart the long running apps that use it! /usr/lib/gstreamer-0.10/libgstaudioconvert.so was updated, restart the long running apps that use it!
