Hi Dominik,

Please check line 30 in shp_to_obs.py,
QtCore.QObject.connect(self.Next, QtCore.SIGNAL("clicked()"), shp_to_obs.Next)

ShowDialog1 class doesn't know shp_to_obs instance.
Please try like following,
    line 152-:
     dlg1 = ShowDialog1(self)
     QtCore.QObject.connect(dlg1.Cancel, QtCore.SIGNAL("clicked()"), exit)
QtCore.QObject.connect(dlg1.Next, QtCore.SIGNAL("clicked()"), self.Next)

regards

Hello,

I'm trying to write a python plugin to create an input file for an urban
climate model (RayMan) out of three shape files.
Unfortunatelly QGIS closes when I try to load the plugin (Windows, as
well as Linux, both 32bit, version 1.8.0). When I start QGIS from the
Terminal (Ubuntu), I get "segmentation fault" when it happens. Thats all.
Is there some function that is known to crash QGIS or do you have any
suggestions how I could  track down the error?

I put the plugin on our server if that helps. It can be downloaded from
http://www.urbanclimate.net/shp_to_obs.zip.

Best regards!
