Marc;
  I reviewed this bug report and I don't think there is enough information to determine the source of the problem.  The error message you are seeing is a common message that is generated when the X server reads the monitor EDID information.

As this seems to be a bug report against the Abode Flash Player, which is not supported here, I am marking the bug as CLOSED/CANTFIX.

I encourage you to look at the page at the URL below which details how to setup flash to run inside the nspluginwrapper.

For additional support, please try either the #fedora channel on freenode or Adobe support.
