Bug#684604: Fwd: [Bug 1075747] Re: Pydev workspaces become corupted after loading them without Pydev installed

[Niels Thykier]

Hi,

I noticed a related bug in the Ubuntu bug tracker.  It might not be
quite the same issue afaict, but it does suggest that workspace can
become "corrupted".  This could explain why a eclipse starts with a
"clean workspace", but not with the original one.
