Description Robert Munteanu 2011-11-14 15:50:47 EST

What steps will reproduce the problem?
1. Perform a pull from the repositories view
2. Double-click a commit in the resulting dialog
3. Close the pull result dialog
4. In the commit editor, double-click a file and try to open it

This does not always happen, but it did for the org.eclipse.mylyn.reviews git repository and commit  62f7b951f733e841d1e5c50348d549ab07e7a8ff . 

The NPE occurs when double-clicking on any of the file entries. Reopening the commit , e.g. from clicking the hyperlink in this bug report, and trying to open the files does not yield the NPE.
