media_plugin_webkit on linux is broken

media_plugin_webkit always gives this error on Linux:

WARNING: LLPluginInstance::load: apr_dso_load of /home/user/Downloads/exodusviewer-12.8.9.1/bin/llplugin/libmedia_plugin_webkit.so failed with error 20019 , additional info string:
/home/user/Downloads/exodusviewer-12.8.9.1/bin/llplugin/libmedia_plugin_webkit.so: undefined symbol: _ZNK3JSC6JSCell14isGetterSetterEv

Replacing plugin_media_webkit.so with the official viewer's version, or compiling the official viewer and copying that over, works correctly.

This is of significant importance due to the ongoing integration of webkit in the viewer. A workaround exists via the use of http://search.secondlife.com/ and http://my.secondlife.com/ in an external browser.
