hgview #10131500 Still references to instabilities [open]

There are still places in the code refering to instabilities resulting in the error message

AttributeError: 'workingctx' object has no attribute 'instabilities'

It worked for me by changing to troubles instead of instabilities in
- qt4/hgrepomodel.py:272: elif ctx.troubles(): # instabilities():
- qt4/revision_description.py:228: troubles = ctx.troubles() # instabilities()
