[Sugar-devel] Use ObjectChooser filtering by activity

[Gonzalo Odiard]

Replaying to myself.

Filtering by activity have a problem right now: show the objects in the
journal filtered by activity.
While solve the Read problem, and probably is good for Jukebox,
is a problem by example for ImageViewer and Paint.
Both can open images, but like the Journal filter by activity, will show
only
the images opened the last time by the activity used as filter.
Example:
* Draw something with Paint
* In the Journal will be seen filtered by Paint but not by ImageViewer.
* Open the same draw using ImageViewer
* In the Journal will be seen filtered by ImageViewer but not by Paint.

I think this is a bug, not a feature.

What you think about switch to filter by all the mime type the activity
selected can open?
