Exception thrown when trying to debug Django application.

[borfast]

I just installed bugjar in Ubuntu 13.04 to give it a try at debugging a Django application but I'm getting an exception thrown when I try to execute it with bugjar ./manage.py runserver.

This is the whole error:

(my_project)borfast@computer:~/projects/www/my_project$ bugjar ./manage.py runserver --settings=my_project.settings.local

self.lexer = kwargs.pop('lexer')
KeyError: 'lexer'

Any thoughts on what could be the cause and how to fix it?

This looks like a bug caused cricket 0.1.0's packaging. I fixed bug #1 yesterday, which required pushing an update to tkreadonly, but the bugjar 0.1.0 installer doesn't specify a version requirement for tkreadonly.

The immediate fix:

pip uninstall tkreadonly
pip install tkreadonly==0.5.1

The longer term fix: update tkreadonly to handle the pop('lexer') call better. I'll issue an update to correct that problem.

[freakboy3742]

I've just uploaded tkreadonly 0.5.3 which should correct this issue. If you run

pip install -U tkreadonly

you should get the fix; or, if you install bugjar from scratch, you'll get the fix too.

That did the trick indeed. Thanks @freakboy3742!
