pycrypto issue?

[Bryan Schmersal]

I've run into a situation where verifying signatures against a key is throwing "Plaintext too large".
I've attached the code that I'm using.
Run against the stock pycrypto install, I get:==> ./check_rsa.pyCrypto version = 2.6.1Generating 15 keys....done   Sig V  Key >              Sig >  Key V+-E--EEE----E-E f= 8 e= 6 +-------------- f=14 e= 0 -+------------- f=14 e= 0 -+------------- f=14 e= 0 --+------------ f=14 e= 0 E-+----------E- f=12 e= 2 ---+----------- f=14 e= 0 ---+----------- f=14 e= 0 ----+---------- f=14 e= 0 ----+---------- f=14 e= 0 -----+--------- f=14 e= 0 E----+----E--E- f=11 e= 3 ------+-------- f=14 e= 0 E-----+------E- f=12 e= 2 -------+------- f=14 e= 0 E------+------- f=13 e= 1 --------+------ f=14 e= 0 --------+------ f=14 e= 0 ---------+----- f=14 e= 0 ---------+----- f=14 e= 0 -----E----+---- f=13 e= 1 ----------+---- f=14 e= 0 -----------+--- f=14 e= 0 -----------+--- f=14 e= 0 ------------+-- f=14 e= 0 E-----------+-- f=13 e= 1 --E--EE------+E f=10 e= 4 -------------+- f=14 e= 0 --------------+ f=14 e= 0 E------------E+ f=12 e= 2 ==> 
+ means that the signature was verified, - means that verification failed and E means that the code caught "Plaintext too large".
So I grabbed the pycrypto sources, compiled the package and ran the tests there:(crypto)==> ./check_rsa.pyCrypto version = 2.6.1Generating 15 keys....done   Sig V  Key >              Sig >  Key V+-------------- f=14 e= 0 +-------------- f=14 e= 0 -+------------- f=14 e= 0 -+------------- f=14 e= 0 --+------------ f=14 e= 0 --+------------ f=14 e= 0 ---+----------- f=14 e= 0 ---+----------- f=14 e= 0 ----+---------- f=14 e= 0 ----+---------- f=14 e= 0 -----+--------- f=14 e= 0 -----+--------- f=14 e= 0 ------+-------- f=14 e= 0 ------+-------- f=14 e= 0 -------+------- f=14 e= 0 -------+------- f=14 e= 0 --------+------ f=14 e= 0 --------+------ f=14 e= 0 ---------+----- f=14 e= 0 ---------+----- f=14 e= 0 ----------+---- f=14 e= 0 ----------+---- f=14 e= 0 -----------+--- f=14 e= 0 -----------+--- f=14 e= 0 ------------+-- f=14 e= 0 ------------+-- f=14 e= 0 -------------+- f=14 e= 0 -------------+- f=14 e= 0 --------------+ f=14 e= 0 --------------+ f=14 e= 0 (crypto)==>

Any thoughts on why there's a difference between the two installs?
Thanks,Bryan
