Blender Version
Broken: 2.75a c27589e
Worked: Not sure, the file is at least 5 years old from when Blender had the old-style interface.
Upon loading Blender crashes with the backtrace shown below.
I've managed to workaround this bug by altering line 494 of view3d_draw.c to the following:
const int sublines = v3d->gridsubdiv? v3d->gridsubdiv : 1;
This allowed me to load the file, so I could set the subdivisions to a sensible value and save.
Exact steps for others to reproduce the error
