StarTeam Eclipse Plugin 13 & Eclipse 4.2 non text chars errors

Hello,

My team uses StarTeam 14 servers and the associated CP.  In addition we run Eclipse 4.2 (Juno) and the StarTeam Eclipse plug-in version 13.0.1. 

All of my team members are receiving this same error in Eclipse.  Every time the StarTeam MPX refresh occurs, for each project in the current workspace we have checked out, we get an eclipse error pop-up window that says "non text chars" as the error.  As I have 7 projects checked out I thus get 7 pop-ups every few minutes.

The details on the error are in the XML below.  Any ideas on how to resolve this?

We also have other issues that have been common for several plug-in versions like incorrectly identifying files as being changed, unable to force checkout files (won't replace read-only files), etc.
