Bug 357608

Description Stephane Begaudeau 2011-09-14 05:49:39 EDT

I am currently using Eclipse 4.2 M1 and Egit 1.0. If I select a project in my workspace and then select Team -> Show in history a NPE occurred in eGit (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=357606) but if I open the history view first and then I select my project to show its history, this error appears:

This issue seems to be somewhat related to this other one: https://bugs.eclipse.org/bugs/show_bug.cgi?id=344861
