[PyQt] Using uic on KUrl has problems with KFile::ExistingOnly

[Shaheed]

Hi,

I'm using PyKDE4, and trying to load Designer .ui files. I have a problem with one file which has the following KUrl widget:

    <widget class="KUrlRequester" name="kcfg_executable">
     <property name="mode">
      <set>KFile::ExistingOnly|KFile::File</set>
     </property>
    </widget>

When I try to load this using the uic module, I get the following error:

Traceback (most recent call last):
  File "./kterminal_example.py", line 43, in create
    self.creator = ExecutableEditor()
  File "./kterminal_example.py", line 21, in __init__
    self.ui = uic.loadUi("Projects/exekutor/src/ExecutableEditor.ui")

    self.wprops.setProperties(obj, branch)
  File "/usr/lib/pymodules/python2.7/PyQt4/uic/properties.py", line 403, in setProperties
    prop_value = self.convert(prop, widget)
  File "/usr/lib/pymodules/python2.7/PyQt4/uic/properties.py", line 368, in convert
    return func(prop[0], **args)
  File "/usr/lib/pymodules/python2.7/PyQt4/uic/properties.py", line 113, in _set
    expr = [self._pyEnumMember(v) for v in prop.text.split('|')]
  File "/usr/lib/pymodules/python2.7/PyQt4/uic/properties.py", line 108, in _pyEnumMember
    raise AttributeError("unknown enum %s" % cpp_name)
AttributeError: unknown enum KFile::ExistingOnly

I have checked that importing KFile (from PyKDE4.kio) in the main program makes no difference, and that importing it from the interpreter 
prompt allows me to print the value of KFile.ExistingOnly. So I guess from this last line that the issue is that the uic module somehow 
needs to know how to resolve the KFile name. Any ideas on how to resolve this issue would be appreciated.

Thanks, Shaheed
