I am using org.eclipse.help in my RCP. And I have come across a strange issue:
Sometimes when I go to Help->Help Contents, I get a window with this:

Note that it does not appears each time. If I refresh or restart the program,
the error will not appear.
It seems someone has the same problem:
http://www.eclipse.org/forums/index.php/m/624477/#msg_624477
But no one solve this.
So, Is there anyone who can help me? Any ideas how to fix this? Thanks!
