cleanup snippets error

[shinglesware]

Running the cleanup_snippets via ./manage.py cleanup_snippets produces the following error for me. Changing line 42 in dpaste/management/commands/cleanup_snippets.py to deleteable_snippets = (deleteable_snippets | onetime_unviewed_snippets) seems to have fixed the issue for me. Please advise if that is the appropriate fix.
