Table containing ForeignKey created with wrong casing — at Version 5

Description (last modified by Ramiro Morales)

Here is the models.py:

class Plugin(models.Model):
	name = models.CharField(max_length=50)
	description = models.CharField(max_length=100)

class PluginContainer(models.Model):
	title = models.CharField(max_length=50)
	plugin_settings = models.CharField(max_length=2000)
	plugin = models.ForeignKey(Plugin)

PluginContainer refers to Plugin object (ForeignKey)
Running manage.py syncdb produces the tables:

App_plugin
app_plugincontainer

notice the incorrect casing on app_plugincontainer.
Removing the ForeignKey from PluginContainer correctly creates the table as App_plugincontainer

This is causing a problem with running manage.py syncdb again as it cannot find App_plugincontainer and then tries to create app_plugincontainer and fails as the table already exists.

My environment:
OS: Mac OS X 10.5
DB: MySql 5.05
Python: 2.5
Django: SVN

MySql's lower_case_table_names variable is set to 2 (default on mac os x)

Cheers
Naren

Unable to get any response on user groups.
Added some debug statements to syncdb.py and found that the SQL statement being executed did indeed have the correct casing for the table name. However, once again, this problem happens ONLY when the model has a foreign key field. This leads me to believe this is in fact a bug within django and not MySQLdb.
