pythonw.exe crashing

I had some code working previously that is now causing pythonw.exe to crash. I have an .mxd set up that I am using to loop through features in a layer and export the layout to jpeg. However now the script crashes when it gets to df.zoomtoselectedfeatures. Here is what I have:

import arcpy  Path = os.getcwd() GSP_Join = "C:\\Users\\TDMC0\\AppData\\Local\\Temp\\scratch.gdb\\GSP_Join"  mxd = arcpy.mapping.MapDocument(Path + r"\GasLeaks2013.mxd") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] Layer = arcpy.mapping.ListLayers(mxd, "", df)[0] Layer2 = arcpy.mapping.ListLayers(mxd, "", df)[1] Layer3 = arcpy.mapping.ListLayers(mxd, "", df)[2]  # Create a search cursor try:      rows = arcpy.SearchCursor(GSP_Join, "", "", "CONN_OBJ_ID_NUM", "CONN_OBJ_ID_NUM")  except Exception as e:      print e  # Iterate through the Implausible Reads Feature, getting and zooming to respective extents and exporting layout to JPEG. currentState = " " count = arcpy.GetCount_management(GSP_Join) progress = 1  for row in rows:       try:                           if currentState != row.CONN_OBJ_ID_NUM:                print "\rExporting Data Driven Pages to JPEG...%s of %s" %(progress, count)                currentState = row.CONN_OBJ_ID_NUM                where_clause = "\"CONN_OBJ_ID_NUM\"=" + "'" + currentState + "'"                arcpy.SelectLayerByAttribute_management(Layer, "NEW_SELECTION",  where_clause)                df.zoomToSelectedFeatures()                df.scale = 5500                arcpy.RefreshActiveView()                arcpy.SelectLayerByAttribute_management (Layer, "CLEAR_SELECTION", "")                Layer.definitionQuery = where_clause                Layer2.definitionQuery = where_clause                Layer3.definitionQuery = where_clause                arcpy.mapping.ExportToJPEG(mxd, r"E:\GasLeaksProject\2012\JPEG\CONN_OBJ_ID_NUM" + str(currentState) + ".jpeg", resolution=300, jpeg_quality=70)                Layer.definitionQuery = ""                Layer2.definitionQuery = ""                Layer3.definitionQuery = ""                progress = progress + 1                      except Exception as e:           print e

When I run this I get a Windows OS message saying "pythonw.exe has crashed". I narrowed it down to the line df.zoomToSelectedFeatures() (if I comment out this line the code runs but obviously does not output what I want). Again this was working previously (about six months ago) I must have tested it a hundred times. All of the data sources are working in the mxd, and I tried re-saving the mxd and pointing to the new copy but no luck. I also printed my where_clause and it looks good. It must be a problem with my "list data frames / list layers code". Any help would be appreciated.
