[Sugar-devel] web-activity: env.getEnvironment dependency with Python code

[Daniel Narvaez]

Since I replied twenty times to myself and probably confused everyone...
Let me try to summarise. I think it make sense to

1 Test if the approach you suggested works. I think it didn't when I
tried but it's certainly worth another try.
2 If load_started doesn't work, send email to the webkitgtk mailing list
and see what they suggest.

Thanks for looking into this, the current implementation is certainly not
very nice.
