Error handling itself raises a TypeError due to wrong # of arguments (overloading appears not to be working)

[GoogleCodeExporter]

when i try to place an invalid order via placeOrder, IbPy attempts to send me 
an EClientErrors.FAIL_SEND_ORDER but fails; the attempt to send the error 
itself has an error.

i get:


error trace:

bit at line 789:)

one workaround appears to be to go to all of the times that error is called in  
EClientSocket.py within an "except" clause and replace each instance with
  self.close(); raise

i used interactive search and replace in vi: %s/self.error(/self.close(); 
raise; self.error(/gc

now an informative error trace is raised
