Did then commit you ran into this issue on not have an author line?
The file in question was last updated in a merge commit a week ago. It looks like it has an Author line on each commit.
This bug is more problematic than I had originally thought. It keeps occurring on the drawing thread which leaves the eclipse workspace half-drawn and leaves the UI unusable (it doesn't respond the UI inputs).
Can you try the current patch at: http://egit.eclipse.org/r/#change,3681 and see if it resolves the issue for you?
With that patch the NPE issue is resolved however the file is only partially annotated. There are blocks that have no annotations. These blocks are sections that haven't been modified since the initial revision of the file, cgit blame shows them as ^shaid instead of just shaid.
On further investigation I found that the RevCommit (e.g. BlameResult.getSourceCommit()) for lines that had not changed since the initial commit is null. That seems to be an issue with the jgit blame generator (or perhaps the client is supposed to then work out what the initial commit for the file was).
Is the file you are seeing this issue on in a public repository? If not, can you describe the history a bit, such as 5 revisions, 2 merges, etc., I'd like to reproduce this locally.
