Moving this to MythTV users where I believe it belongs.

This is likely the bug that exists in some versions of the Adobe Flash 
Player plugin. These broken versions of the plugin assume they are being 
called by a GTK based application that has already done the necessary 
GTK initialization as part of the application. However, since the plugin 
can be called by a non-GTK application, this assumption is not valid. In 
particular, since WebKit, Qt and MythTV are not GTK based software, none 
of them did the initialization on behalf of the plugin.

A workaround was added to WebKit in changeset 
<http://trac.webkit.org/changeset/61307>. This commit is not in Qt 4.6's 
WebKit but is in Qt 4.7's Webkit.
