Usually because: 1) You have the contrib.contenttypes table in your database 2) You have added an application to the project 3) The content type IDs that were allocated in the original application don't match the new application. The only reliable solution is 'don't serialize the contenttype app'. The contenttypes are allocated as part of the syncdb process, so serializing them generally isn't required anyway; in your particular case, the difference in the order in which contenttypes are allocated is the cause of the loaddata problem. This leaves one minor issue - if you have models that reference content types (for example, generic foreign keys). This is a known issue, for which there really isn't a good solution - suggestions are welcome on how this should be worked around.
