IntegrityError while importing example database

[konr4d]

When importing example database I get:
IntegrityError: Could not load cms.Page(pk=1): duplicate key value violates unique constraint "cms_placeholder_pkey"

Whole trace:

I am assuming that you are importing the example database into an existing database - in that case you may well get some conflicts with existing placeholders.

I'd like to close this - can you confirm that this issue only occurred when loading the example database fixture into an existing database?
