Eclipse Internal error makes it impossible to use git

Question

I am banging my head since yesterday on a problem that popped up after i switched branch on my Android git-managed project, an error pop-up keeps showing making it impossible to use git

Eclipse's log shows :

!ENTRY org.eclipse.core.jobs 4 2 2014-11-27 12:05:44.993
!MESSAGE An internal error occurred during: "Computing Git status for repository git".
!STACK 0

I tried various attempts to fix it :

• Uninstalling EGIT from Eclipse via MarketPlace the process seems good but after restart, EGIT's still there.
• Deleting it manually by removing it from plugins and featuresfolders as suggested on other posts.
• Starting a fresh Eclipse install and importing git projects, the problem shows off right after the project are added.
• Cloning my GIT repo into another location in a new workspace same problem.
• I couldn't find the exact version of org.eclipse.jgit.treewalk.WorkingTreeIterator to check on what the NPE happens

It seems to like if my GIT repo was corrupted, any help would be much appreciated.

EDIT I don't know if it's relevant but here's Session data :

eclipse.buildId=4.4.1.M20140925-0400
