Created attachment 459 Proposed patch
Created attachment 460 Updated proposed patch Fixes indentation (mixed tabs and spaces > spaces) in plugin_button_clicked function. One might want to fix the rest of the file, it should be easy to do a search and replace.

This bug has been fixed for some time in SVN.
