Failure to Run with Latest TexLive

The minimal example fails with the latest texlive with the following error message. The issue occurs due to the patchcmd failing in \patchcmd{\beamer@title} here. My guess is that this is due to some change in the nature of the command. In specific, either \def\inserttitle{#2} not existing, or not be patchable anymore.
