[Blink] segfaults and no sound devices

[Julian]

I have packaged [0] Blink under Exherbo Linux [1]. But when I start it,
I observe two problems:
* there are no sound or video devices showing up
* when trying to make an actual call, blink will eventually segfault

The segfault is here after clicking twice on a contact:
============= TRACEBACK 1 ===========================
Traceback (most recent call last):
  File

sipsimple.core._core._pj_str_to_str (sipsimple/core/_core.c:59778)
MemoryError
Segmentation fault
=====================================================


Additionally, when I enter the video section under preferences, it throws:
============= TRACEBACK 2 ===========================
  File
"/usr/x86_64-pc-linux-gnu/lib/python2.7/site-packages/blink/preferences.py",
line 480, in eventFilter
    self.camera_preview.producer = SIPApplication.video_device.producer
AttributeError: 'NoneType' object has no attribute 'producer'
=====================================================

Then, when leaving the video section, it throws:
============= TRACEBACK 3 ===========================
Traceback (most recent call last):
  File
"/usr/x86_64-pc-linux-gnu/lib/python2.7/site-packages/blink/preferences.py",

sipsimple.core._core._get_ua (sipsimple/core/_core.c:81654)
sipsimple.core._core.SIPCoreError: PJSIPUA is not instantiated
=====================================================

This suggests it's something with sipsimple. I use version 2.6.0.
Cython is version 0.23.4, but I also tried with an older one, which
didn't help. Python is version 2.7.11.

Mind that sound works fine everywhere else, including things like
mumble, teamspeak, steam and so on.
