po object results in error: cannot find interface declaration for '$__lldb_objc_class'

Question

I'm having this weird functionality in the debug console.

say you have the following code:

anIssue.issueID=[issueDictionary objectForKey:@"uniqueId"];

the po of the issueDictionary function correctly:

{ Title = "december 2012"; coverUrl = "htt://toeete.com/CoverURL/77111a51-32d8-4c39-912e-a889bad250e6.png"; downloadUrl = "htt://oetoeto.com/pdfFile/TR December 2012 Single.pdf"; "end_date" = "12/31/2013"; images = ( ); "release_date" = "02/26/2013"; summary = "december 2012 issue"; uniqueId = "december 2012_1"; updated = "02/11/2013"; }

But whenever i try to print-object of "anIssue.issueID" or "[issueDictionary objectForKey:@"uniqueId"]" it fails with: error: cannot find interface declaration for '$__lldb_objc_class'

say like :

po [anIssue issueID]

or

po [issueDictionary objectForKey:@"uniqueId"]

both fails with the error... Though if i

po anIssue

It succeeds!!!!!!!!

: ID=december 2012_1 Title=december 2012 Released=2013-02-25 22:00:00 +0000 Free=YES Description=december 2012 issue

Any idea

Xcode 4.6.1 was released a couple of days ago and a couple of problems that would lead to people getting cannot find interface declaration for '$__lldb_objc_class' have been resolved. Please try updating to Xcode 4.6.1 if you're seeing this problem.
