test and syncdb failed (Django 1.4, Windows 7)

[taivo]

Running the glamkit-eventtools test suite yields the error message below. When I copy the code for ExampleVenue, ExampleEvent, ExampleOccurrence from tests\eventtools_testapp into my models.py and run syncdb, I get the same error.

This error occurs in both the ixc branch and this glamkit branch.

Relevant specs:
Django 1.4
Windows 7
glamkit-eventtools v2.0.0a1
