TypeError: CkCert_LoadFromBinary() takes exactly 2 arguments (3 given)

[GoogleCodeExporter]

1. Added androguard and chilkat to pythonpath (tried both in winodws and linux, 
same outcome)

2. Created a new phyton script (these are the relevant lines):
from androguard.core.bytecodes import apk
a = apk.APK(apkfilename)
status, cert = a.get_certificate("META-INF/CERT.RSA")

Got the following error:
Traceback (most recent call last):
  File "C:\Users\retracted\workspace\androguard\test.py", line 53, in <module>
    status, cert = a.get_certificate("META-INF/CERT.RSA")
  File "C:\androguard-1.9\androguard\core\bytecodes\apk.py", line 542, in get_certificate
    success = cert.LoadFromBinary(f, len(f))
  File "C:\Python27\lib\site-packages\chilkat.py", line 1928, in LoadFromBinary
    def LoadFromBinary(self, *args): return _chilkat.CkCert_LoadFromBinary(self, *args)
TypeError: CkCert_LoadFromBinary() takes exactly 2 arguments (3 given)

This is Python 2.7 on Winodws 7.

I don't know much about Python but the error seems to be with the apk.py since 
it gives the wrong amount of arguments, correct?

I found the problem: in Androguard 1.9, CkCert.LoadFromBinary() is called, but 
LoadFromBinary2() is the correct method. This seems to be fixed in the 
repository already.

I cloned the latest repository and the LoadFromBinary2() is used, but another 
TypeError occured:

I got the same error as #2

I think we can fix the problem as following : 

    def get_certificate(self, filename):
 558         """
 559             Return a certificate object by giving the name in the apk file
 560         """
 561         import chilkat
 562 
 563         cert = chilkat.CkCert()
 564         f = self.get_file(filename)
 565         data = chilkat.CkByteData()
 566         data.append2(f, len(f))
 567         success = cert.LoadFromBinary(data)
 568 
 569         return success, cert
