Thanks Jakob, for me there aren't no deadlocks anymore in any type of
intersection, including roundabouts.
The main "difficulty" was to change lane connections in intersections from
netedit, as lanes with no connections are shadowed by the intersection
polygon as in the picture below and locate them can be tricky. This is just
an stylistic remark though.

Regards,
Alejandro
