Invalid Topology [Undetected intersection.]

I am trying to use the clip tool to cut thematic polygons with each polygon feature class, defining district boundaries. For some district polygons, I'm getting the following error message:

ERROR 999999: Error executing function.
Invalid Topology [Undetected intersection.]
Failed to execute (Clip).

I don't understand this message because the two layers are well overlapped. Any ideas on how I can solve this problem ?

Thanks in advance.
