[Dbix-class] DBIx::Class - Create

[Ben Tilly]

Looking at the source code for the module, there is a check for
freeze/thaw causing the problem that should get an explicit error
message telling you how to fix it.  If there is no such message, then
it is likely that something else went wrong.  (Or you have an old
version of the module.)
