Hi I'm running PyWPS service with some processes. Everything is working fine bud i wanted to try Qgis plugin WPS client and problems showed up.

First thing is that my process takes a while but Qgis ends with "Timed out" even if statusSupported is set to True. The only way i found to deal with this was enlarging the time limit in Qgis for network. But i don't think that's the way it should work.

Second is error which I get when process is done. Process returns geotiff With statusSupported=true, storeResponse=True and useMapscript=True/False (both).

All these attemps ends with error:

traceback (most recent call last):
  File "/home/gis/.qgis//python/plugins/wps/QgsWpsDockWidget.py", line 816, in resultHandler
    return self.errorHandler(resultXML)
  File "/home/gis/.qgis//python/plugins/wps/QgsWpsDockWidget.py", line 968, in errorHandler
    QMessageBox.critical(self.iface.mainWindow(), "Exception report", exceptionHtml)
TypeError: arguments did not match any overloaded call:
  QMessageBox.critical(QWidget, QString, QString, QMessageBox.StandardButtons buttons=QMessageBox.Ok, QMessageBox.StandardButton defaultButton=QMessageBox.NoButton): argument 3 has unexpected type 'NoneType'
  QMessageBox.critical(QWidget, QString, QString, int, int, int button2=0): argument 3 has unexpected type 'NoneType'
  QMessageBox.critical(QWidget, QString, QString, QString, QString button1Text=QString(), QString button2Text=QString(), int defaultButtonNumber=0, int escapeButtonNumber=-1): argument 3 has unexpected type 'NoneType'

Unfortunately I have no idea what does it mean. Thanks for any clue.

Here is initialization of process and definition of the output. Whole process is pretty long and this should be enough. http://pastebin.com/d750FWQF
