An internal error occurred during: "Compute launch button tooltip".

Hello,

We are experiencing quite an annoying issue with the GNU Toolchain for Blackfin Eclipse plugins. We're running a customized version of the TLL 0.5.3 Fedora 17 image (for Northeastern University), with Blackfin GNU Toolchain Integration v. 1.0.5.201205011311. Please provide a fix/solution!

Steps to reproduce

1. Launch Eclipse
2. In C/C++ Perspective, click anywhere on 'Project Explorer'
3. However mouse over one of the run/debug icons

Result

An error dialog showing a problem occured appears. This is extremely annoying and can happen several times a minute with normal Eclipse usage.
