VIM plugin for RubyMine - Java exception

Hi,
  Just installed the VIM plugin. The vi functionality seems to work great - and much appreciated.
  However, when I bring up the Help screen, for example, it throws a Java exception, and nothing is displayed.  The same thing happens on Windows, Mac, and Linux.  Any ideas on how to get around this?  Although the error log mentions DefualtSearchEngine - I've confirmed that my default search engine is set, and does work in other contexts.

The error log from the Linux console follows.  Thanks for any help...
