Latest Pysmi 1.5.1 produces MIB compilation error

[umair-zink]

Expected behavior

compiler.addMibCompiler(mibBuilder, sources=['http://mibs.snmplabs.com/asn1/@mib@'])

should work without any errors

Actual behavior

root@2a66d39a64fa:/usr/app/src# python pysnmp_listen.py
Traceback (most recent call last):
File "/usr/app/src/pysnmp_listen.py", line 40, in

Detailed steps

Not sure if its a bug or not, but I was using the latest pysnmp with pysmi 1.5.0 till last week and they were working fine, but today i built my docker and it pulled up the latest pysmi 1.5.1 and it started giving me the MIB compiler error on the same code which was working last week.

Changing pysmi back to 1.5.0 works fine again.
