I tried to use the new synchronize view (egit version 0.9.3). Everytime I try to synchronize my local repo (<local .git> with the remote repo (origin - master) I get an error; the following log statement occurrs:

!ENTRY org.eclipse.team.core 4 4 2010-09-17 20:31:00.031
!MESSAGE Errors have occurred while calculating the synchronization state for Git without local changes.

This issue will only occur when initial commit is included in comparison. Unfortunately I can't reproduce this issue in my environment. 

I think that this path should fix it:

Should be fixed with e6fdf8d71ce861a350be53474d4c4a21454cd97e.

Check tomorrow's nightly.
