[Pkg-openssl-devel] Bug#742152: _ssl.c:1415: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac

[Sascha Schmidt]

Package: openssl
Version: 1.0.1e-2+deb7u4
Severity: important

I was developing a webservice client in python. After a while I hit the situation where I had to
transfer files from a https webserver using a supplied 3rd party sdk.

After seconds of transferring data my app crashes with an error which displays the following informations:
[...]

  File "/usr/lib/python2.7/httplib.py", line 561, in read

    s = self.fp.read(amt)

I googled around and often noticed the problem/bug reports for openssl.
There's no fix I can provide but I've read a lot that is seems to be a problem with the openssl (python?) package...

Is there something I can do to investigate this problem?
