 Refreshing a map in Print Composer that has a vector layer rendered in
 symbology-ng mode causes qgis to abort with the following message:


 {{{
 Warning: Qt has caught an exception thrown from an event handler. Throwing
 exceptions from an event handler is not supported in Qt. You must
 reimplement QApplication::notify() and catch all exceptions there.

 terminate called after throwing an instance of
 'pal::PalException::LayerExists*'
 Aborted

 }}}
 I heard that currently Print Composer does not work with symbology-ng
 mode, so I suggest that users should be prevented from using Print
 Composer by showing a dialog that Print Composer is currently disabled in
 symbology-ng mode.
