27105	Misleading error in ContentTypes get_for_model	Andy Baker	nobody	"This (line 75):

    except (OperationalError, ProgrammingError, IntegrityError):

is gives the following message:

                ""Error creating new content types. Please make sure contenttypes ""
                ""is migrated before trying to migrate apps individually.""

However - it's catching a much broader set of issues. I was baffled for a while - my actual issue was that MySQL was unstable: ""Lost connection to MySQL server at 'reading initial communication packet"" but I had to disable the exception handling to figure that out.

We should probably examine the error inside the except block and narrow down the range of cases that result in this message. "	Cleanup/optimization	closed	contrib.contenttypes	1.9	Normal	fixed			Unreviewed	0	0	0	0	0	0
