To add to Joe's good advice, I'd say to insert some screws across the 
break to add strength.  Countersink so the screw head is below the 
surface.  Putty over the screw heads/touchup.
If you insert the lag screw and there is dried glue in there, it will 
tend to split again.
Remember there is liability if the leg fails and it tips over.  If you 
leave it in questionable condition, you might find yourself in a bind later.
Good luck.
