[news.eclipse.newcomer] Re: Mylyn New Local Task Failure

["Darin Swanson" <Darin_Swanson@xxxxxxxxxx>]

Mylyn has a bug.
With a search I found: https://bugs.eclipse.org/bugs/show_bug.cgi?id=248683 
which is fixed for 3.0.3

In the future, start with a search the Eclipse bugzilla for a similar bug 
report: https://bugs.eclipse.org/bugs/query.cgi
If you do not quickly find a matching report, ensure to log a bug report to 
make sure the problem is known and addressed.

Also for Mylyn questions, the eclipse.tools.mylyn newsgroup is the 
appropriate forum (I have cc'd that newsgroup)

Thanks for reporting the problem
