Hi all.
I'm working on a PyQt-based application. I decided to load ui files dynamically
using uic.loadUi function and it just worked since my last PyQt4 upgrade (I was
using PyQt4 4.7.3). With 4.7.7 I notice the following error while attempting to
load a ui file:

if path[-1] in "/\\":
TypeError: 'in <string>' requires string as left operand, not QString
(on Windows XP virtual machine)
They're different errors but probably both of them are cause by the following
code lines (from PyQt4.uic.Loader.loader):
...
def loadUi(self, filename, toplevelInst=None):
self.toplevelInst = toplevelInst
# By using QFileInfo.path() rather than os.path.dirname() we allow
# QString file names.
return self.parse(filename, QtCore.QFileInfo(filename).path())
In 4.7.3 there was only a parameter into the parse method, but in this new
version, the second parameter (a QString) is used for various operations
related to os.path python standard module (that require str).
In my case, replace the last row with the following, just works:
return self.parse(filename, unicode(QtCore.QFileInfo(filename).path()))
I don't know if this can break other parts of uic. Tell me if I'm doing
something wrong :)
