A quick help for people who are developing GWT (Google Web Toolkit) applications on Mac OS X. GWT uses Safari for its development hosted mode. When I tried to ran it today, I got the following error message: "GWT quit unexpectedly while using the libgwt-ll.jnilib plug-in".

The problem has been fixed but will not be pushed until Safari 4.0.5. The bug report can be found here.

And a solution is posted in the comments.

Hope this helps out anyone experiencing this problem. It is not your code! I also thought that it was due to a coding error. in fact many thought so.
