 Hi,

 testing latest 6.5svn nightly wingrass build.

 If you open the wxGUI cartographic composer and pick 'add map element'
 then 'North Arrow' you get a pop-up Error message window (screenshot
 attached), twice, and the following different error message in the wxGUI
 command console module output window:

 {{{

 and no image selection gui window. On my linux it works.

 (the first half of the above is very similar to the traceback error in
 #1959)


 thanks,
 Hamish

 ps- todo: replace those eps with native GRASS symbols
