   Here is a debug message from trying out the plugin in a debug build
   with two shapefiles:


   2/19/08 8:59:43 AM [0x0-0x13d13d].org.qgis.qgis[93141] An error has
   occured while executing Python code:

      John,

      I can't test your point 2 due to missing access to a Mac Box.
      Perhaps someone else can take a look at John's porblem?

      Horst,

      The first problem below was resolved by Gary Sherman. I had an
      older 
      version of the Plugin Installer in the plugin folder. Removing
      that 
      allowed the built-in installer plugin to run, and that fixed the 
      permissions problem.

      Still no luck with problem 2 at this point. I tried on my ubuntu
      vm 
      and the menu worked as expected, so this may be a mac-specific
      issue.

      Cheers,
      John
