Instantiation of MailFolder class fails on regexp compilation in python 2.7 #2

Closed thegovyadina closed 8 years ago

thegovyadina commented 9 years ago

Program terminates before connection to server is established. There's an issue with regexp compilation in MailFolder.__init__() method. I got this only in 2.7. Python 3 doesn't raise an error here. UPDATE. Looks like this appears in 2.7.5 and earlier versions.

Traceback (most recent call last):

I use cpython 2.7.6 for testing and i don't see this error. Are you using cpython or something else ?

thegovyadina commented 9 years ago

Yes, I use CPython. I tried 2.7.6 too and it worked fine. According to Python 2.7.6 release changelog they fixed some internal bugs in regexp engine. I guess, that's the reason.

This is a bug in python, not imapy.
