An internal error occurred during: "Reading history from Git". #68

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. For a file in my repository, do team->show resource history
2. Deselect all filter-buttons, so show only the versions for that single file

It is a very large repository for which this happens, it is a repository
that I created by converting a cvs-repository to git, using git cvsimport.
I can browse this repository using git gui, there seems nothing wrong with
the repository itself.

What is the expected output? What do you see instead?
I expect the filtered list of commits to show up in the history view, but
instead I get an error: An internal error occurred during: "Reading history
from Git".  See stacktrace below.

What version of the product are you using? On what operating system?
egit-0.4.0 on eclipse 3.4.1

Please provide any additional information below.

There is another error that is probably related:

When I look in resource history for the complete repository, then I can click 
on the
versions, and see what files were changed in each commit.  This works for the 
most
recent commits, but when I try it on an old one I get the following exception
