[Qgis-developer] QGIS 0.9 on windows:QgsApplication.setPrefixPath() has an invalid type

[Jesse Ayers]

Here you go:

>>> from qgis.core import *
>>> str(QgsApplication.prefixPath())
'<PyQt4.QtCore.QStringRef object at 0x00BA1DF8>'
>>> QgsApplication.setPrefixPath("C:/Program Files/qgis0.9.0preview1", True)

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    QgsApplication.setPrefixPath("C:/Program Files/qgis0.9.0preview1", True)
TypeError: argument 1 of QgsApplication.setPrefixPath() has an invalid type
>>> str(QgsApplication.prefixPath())
'<PyQt4.QtCore.QStringRef object at 0x0318C6F0>'
>>> 


Thanks!
