Got failure: ImportError: cannot import name str_to_unicode

edit

• Hi all!
• I am trying to setup askbot on an ubuntu server.
• I use PostgreSql as my database.
• I got such error information when I executed:
• python manage.py runserver 0.0.0.0:9413 >
• cannot import name str_to_unicode
• Unhandled exception in thread started by <bound method="" command.inner_run="" of="" <django.contrib.staticfiles.management.commands.runserver.command="" object="" at="" 0x9401d4c="">> Traceback (most recent call last):

And the process stuck here without any progress. Is it possible that askbot0.7.48 is not compatible with django-1.5?
