I fixed the above error by filling in the [tasklist] and [ticket-custom] sections of the trac.ini. However, I've now got this error:

SystemError: Parent module 'tasklist' not loaded

Replying to sunit:

I fixed the above error by filling in the [tasklist] and [ticket-custom] sections of the trac.ini. However, I've now got this error:

I'm not exactly sure why you are seeing that error, but it is failing on the pprint line, which is a debug statement that will be commented out in the next commit.

(In [9681]) Raise an error if the custom ticket field has not been defined in the ticket-custom section of trac.ini. Bumped version to 0.1.2. Fixes #4786.
