geodjango access violation on vista 32 bit

Am having a real problem with the geodjango saving an entry. It produces a "Error: Access Violation reading 0x???????" The error does not indicate which file or folder it's trying to gain read/write access to.

Upon researching i found other non-django programs that also have this issue, some were fixed by turning off Vista's DEP controller, but am a bit scared to go down this route and am not even totally sure if this would fix the issue.

Any one got any ideas....? Vista is a nightmare to work on.

Below is error output: Python 2.5.4 (r254:67916, Dec 23 2008, 15:10:54) [MSC v.1310 Type "help", "copyright", "credits" or "license" for more in (InteractiveConsole)

Right In case anyone else ever has the issue.. The problem was following a doc referenced at: http://code.google.com/p/geodjango-basic-apps/wiki/FOSS4GWorkshop

if you install GDAL from binary or install PostgreSQL 9.0 DO NOT reference the GDAL dll file in your settings.py. Always go with setting the VARIABLE_DEFINITION in windows system's PATH.

The culprit was this in settings.py: GEOS_LIBRARY_PATH='c:\geodjango\gdal\bin\geos_c_fw.dll'

You seems to have answered your own question. Thanks for the suggestion. I had a similar issue as well. I also had a line like:

GEOS_LIBRARY_PATH = r'C:\OSGeo4W\bin\geos_c.dll'

(Hijack the topic for a while. I know people have problems with finding a working geos binary distribution on windows. After several tries, seems OSGeo4W's distribution works for me. But I read on other people's blogs that some other distribution instead of OSGeo4W's works on their machines.)

So I remove this line and add C:\OSGeo4W\bin\geos_c.dll to system's PATH environment variable. After that, it works fine. So this confirms Tuscan's solution. Hopes it can help people running into the same issue.
