[Bug 1013798] Re: Blink SIP client segfaults with libgcrypt11 1.5.0-3ubuntu0.1

[gdi2k]

Thanks for finding the cause of this.

I have reported the issue to AG Projects via their support email, I hope
they're able to fix it eventually.

Meanwhile I would be very interested in using the workaround you
describe - downgrading libgcrypt11.

When I try this, it wants me to remove a lot of essential packages:

gdi2k at x200-1204:~$ sudo apt-get install libgcrypt11=1.5.0-3

Do you want to continue [Y/n]?

Were you able to downgrade the package without breaking / removing a lot
of other packages?

Title:
  Blink SIP client segfaults with libgcrypt11 1.5.0-3ubuntu0.1

Status in “libgcrypt11” package in Ubuntu:
  Confirmed

Bug description:
  I'm not sure to which package I should report this, but I use the
  Blink SIP client (http://icanblink.com/) and noticed that it segfaults
  at startup if I have libgcrypt11 1.5.0-3ubuntu0.1 installed, but if I
  force the older version 1.5.0-3 Blink works ok.

  Blink is a Python app and I think I managed to find the line of Python
  code that causes the segfault. The line is 'from gnutls.crypto import
  X509Certificate, X509PrivateKey'. Here is what happens when I run it
  in the Python console:

  Python 2.7.3 (default, Apr 20 2012, 22:44:07) 
  [GCC 4.6.3] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  >>> from gnutls.crypto import X509Certificate, X509PrivateKey
  Segmentation fault (core dumped)

  I'm using 12.04, but I originally noticed the issue when I had 11.10
  and the proposed updates enabled. One day there were some updates that
  broke Blink and going through the updates I discovered that reverting
  libgcrypt fixed it.
