liblive555_plugin corrupt after contrib updated to version 2012.08.20

Ever since the contribs updated the live555 library to version 2012.08.20 the liblive555_plugin module is reported as corrupt whenever playing an rtsp url.

OS: Ubuntu 12.04 x86_64 VLC Version: Latest git GCC Version: 4.6.3-1ubuntu5

Whenever I try to open an rtsp url the following is output in the log when in verbose mode:

[0x7faf8c0010f8] main demux warning: cannot load module `/usr/lib/vlc/plugins/demux/liblive555_plugin.so' (/usr/lib/vlc/plugins/demux/liblive555_plugin.so: undefined symbol: _ZN23MediaSubsessionIteratorC1ERK12MediaSession)
[0x7faf8c0010f8] main demux error: corrupt module: /usr/lib/vlc/plugins/demux/liblive555_plugin.so

If I revert my contribs to use live.2011.12.23.tar.gz it works again.
