It works! It works!

How to run it in a non-installed environment:

1. first of all get your new pygobject environment:

$ jhbuild build pygobject

2. Then build grilo from a clean repo

3. Run this command

GI_TYPELIB_PATH+=:/home/vjaquez/checkout/grilo/src/ \
LD_LIBRARY_PATH=/home/vjaquez/checkout/grilo/src/.libs/ \
python ./grilo-test-ui.py

Troubleshooting:

a) if you got this error 

"gi.RepositoryError: Failed to load typelib file
'/opt/jhbuild/lib64/girepository-1.0/foo.typelib' for namespace 'foo: Typelib
version mismatch; expected 3, found 2"

just rebuild gobject-introspection:

jhbuild buildone -c gobject-introspection
