Error encountered checking Geometry returned from GEOS C function "GEOSWKBReader_read_r".

[Valentin Golev]

Hello,

I'm trying to use Django and GeoDjango with SQLite, and Django-
Olwidget for an admin.

I have a model with PointField and I'm using Oldwidget's
GeoModelAdmin for it. I added a new object with a point and it was
created, but then I tried to edit it in admin I got:



GEOSException at /admin/events/uevent/2/
Error encountered checking Geometry returned from GEOS C function
"GEOSWKBReader_read_r".



Please help me, I don't know what to do with it. Maybe I installed
something wrong. Copy-pasted from Exception page:
