[Paraview] Crash with latest CVS

No install. I am trying to run from the build directory by issuing the  
following command:


Line 47 of that file (which ends in .cxx BTW) is the following:

this->addPluginPath( QCoreApplication::applicationDirPath() +  

Which probably won't work for an installation if I understand things  
correctly. We could add:

     //Look in the Application Package "ParaView.app/Contents/plugins
     this->addPluginPath( QCoreApplication::applicationDirPath() +  
QDir::separator() + "../plugins;" );
     //Look for a folder called "plugins" at the same level as  
     this->addPluginPath( QCoreApplication::applicationDirPath() +  
QDir::separator() + "../../../plugins;");

at that would allow for plugins to be loaded from other places, but  
then we are just looking for a particular plugin (pqWidgets) so that  
may not be necessary.

Also, when I try a "make install" the ParaView.app _never_ really gets  
created. I have not had time to troubleshoot this though.
