[Bug 660363] Re: python-qt4 4.7.4 breaks git-cola

[daveinthesky]

I found the issue.  PyQt4 <= 4.7.3 would report bool(QLayout()) == True
while the new 4.7.4 release treats bool(QLayout()) as False.

This is a behavior change, but it's better for the code to be explicit
and check "if foo is None:" instead of checking "if foo:", so it's
likely that it was intentional.

In any case, git-cola 1.4.2.5 works around this and is no longer
affected.
