Description Robin Rosenberg

2011-05-18 18:40:47 EDT

After a workspace refresh, I clicked on the history page. The refresh was due
to a git rebase, so HEAD had changed.

BTW. You can try install EGit directly from latest build #1396[1] it should contain fix for this issue

Thanks,
actually I was talking about https://bugs.eclipse.org/bugs/show_bug.cgi?id=345354
which is different

But it's been like a week since fixed? maybe it's in nightly builds, I'll try but post only on the bug I said instead.
