Alfonso,
I ran into similar types of issues when I was importing data into my
project. I ended up just converting all MultiLine and MultiPolygon
fields into Regular Line and Polygon fields using through a GeoDjango
script (using the 1st Line and Polygon of each feature as the input
for creating new lines and polygons) and putting them into newly
created tables [and renaming everything back...]. None of my imported
data utilized the multi feature, so no data was lost.
The script took a while to run but was quick to write and very simple.
