Hello,

We've developed a custom outline (treeviewer outline). Sometimes this outline is not show correctly, all the text is missing only the triangles (collapse, expand) of the treeviewer are shown.

Reopening the editor does not solve the problem, the editor must be closed and our eclipse RCP application has to be restarted. The below exceptions are shown, can't find anything within issue tracker about the problem.

Kind regards,
Richard
