If downloaded 2.0.1 from Previous versions (not from SVN) on the plug-in page and compared to 2.0 from the plug-in page (not from SVN) they only differ in readme.txt file. So releases appear to have the same bug accross 2.x branch.

Here’s a patch for others who find it difficult to follow descriptive instructions.
