The reporter was digitizing, hit an edge and wanted to pan.  He simply
switched to the pan tool, did that and reactivated the original tool to
continue digitizing.  That didn't work as the input so far was lost and
it even crashed.

That's just because the rubberband was deleted on deactivation.  AFAICS
without the deletion the tool just keeps the state as it should and you
can continue digitizing after doing something else.  Moreover the tool
isn't currently aware that the rubberband might disappear in the
process.
