19221	Cache keys can't be integers	Mark Hughes	Abhimanyu Singh Negi	"In current master cache keys can't be integers whilst they can in 1.4. Attempts to do this result in:

{{{
  File ""/home/ismdj/src/django/django/core/cache/backends/dummy.py"", line 15, in get
    key = self.make_key(key, version=version)
  File ""/home/ismdj/src/django/django/core/cache/backends/base.py"", line 80, in make_key
    new_key = self.key_func(key, self.key_prefix, version)
  File ""/home/ismdj/src/django/django/core/cache/backends/base.py"", line 26, in default_key_func
    return ':'.join([key_prefix, str(version), key])
TypeError: sequence item 2: expected string or Unicode, int found
}}}

The issue seems to have been introduced with this commit:
