sure, install TotalToolbar <http://totaltoolbar.mozdev.org/index.html> 
and Download Statusbar <http://downloadstatusbar.mozdev.org/>.  when in 
customize statusbar (rt click on statusbar), drag the download statusbar 
button onto the palette, and the error will throw.  you'll need to then 
Restore Default Set otherwise things will be mucked, beyond even a 
restart.  (yeah i - or fx - should have some try catch handling.)

set a venkman breakpoint in customizeToolbar.js in wrapPaletteItem(), 
line 225 with the adoptNode(aPaletteItem).  immediately after that call, 
aPaletteItem properties will be inaccessible.  the throw happens a few 
lines afterwards.  not so if you repeat with some other statusbar button.
