Error during Askbot migration from 0.7.48 to 0.7.49

edit

I've made a copy of my current virtual envirtonment with Askbot 0.7.48 and upgraded it using pip: pip install -U askbot All packages were installed successfully with minor warnings.

However I've got this error at the last step:

$ ./manage.py migrate ... Running migrations for djcelery: - Migrating forwards to 0004_v30_changes.

djcelery:0001_initial FATAL ERROR - The following SQL query failed: CREATE TABLE "celery_taskmeta" ("id" serial NOT NULL PRIMARY KEY, "task_id" varchar(255) NOT NULL UNIQUE, "status" varchar(50) NOT NULL, "result" text NULL, "date_done" timestamp with time zone NOT NULL, "traceback" text NULL) The error was: relation "celery_taskmeta" already exists

Error in migration: djcelery:0001_initial DatabaseError: relation "celery_taskmeta" already exists

Is it critical? Any ideas how to fix or w/a it?

Thanks.
