Django errors when removing .pyc files from repo

I have been scratching my head about this for some hours.

I have been pulling me repo on a test server quite happily. The project has quite a few commits. I wanted to clean out all the .pyc files from my repo so deleted them in my master and added *.pyc to .gitignore. That was the ONLY change to the last commit.

Now when I pull to the test server Django fails on an import. However the module is there and there were no other changes apart from the .pyc expunging. So this error is basically bogus.

If I re-add .pyc files it works happily again.

Can anyone shed any light on this?

EDIT:

this is the traceback:

Turns out that __init__.py had made it in as an argument in .gitignore. So all my modules were committed without __init__.py. Whilst the __init__.pyc files were still present these must have been used as a 'fallback' (I didn't realize python did that) so my error was obfuscated. My bad, but I learnt a couple of good lessons.

To clean Django .pyc files execute one or all commands in your terminal:

$ python manage.py cleanup
$ pyclean .
$ find . -name "*.pyc" -exec rm -f {} \;
$ find . -name \*.pyc -delete
$ python manage.py clean_pyc
