Error 000317: Topology within feature dataset cannot be deleted

Description

When attempting to delete a feature dataset containing a topology, an error message is returned. The feature dataset is deleted as well.

Code:
import arcpy
arcpy.env.workspace = r"C:\data\test.gdb"
arcpy.Delete_management("majorrds")

Cause

This is a known issue. The software attempts to warn the user when a topology exists in the feature dataset, which must be deleted before deleting the feature dataset. However, since the topology is a part of the feature dataset itself, it is deleted and the error message is generated.

Workaround

Code:
import arcpy
arcpy.env.workspace = r"C:\data\test.gdb"
try:
   arcpy.Delete_management("majorrds")
   print "copied zoning"
except:
   print "A warning was generated"
