Yes,

I frequently have to work with damaged shapefiles (since my customers
moved from arcinfo workstation to arcgis, they provide me damaged data
layers, can't explain why). The main problem is the one Hamish describes
above.

You can tweak your imported file with various v.clean operations.
Attached is a little script I use to import problematic shapefiles. Fien
tuning the threshold value to your data can give good results. It's a
quick&durty script for my internal use, but the code may help you.

Yours,

Vincent.
