> And consequently, it renders the package unusable. The bug may be related to another package (Python?) since it worked normally a few days ago, and lazygal was not upgraded recently (as far as I remember). My system is mainly testing.

Thanks for reporting.

This is caused by two things :

1) After an update one of lazygal's dependencies, the following
program fails. Maybe it is not good to mix gi bindings with old ones.
--
$ cat gst-import-error.py
#!/usr/bin/env python
from gi.repository import GObject, GExiv2
import gobject
import pygst
pygst.require('0.10')
import gst
$ ./gst-import-error.py
Traceback (most recent call last):
  File "./gst-import-error.py", line 7, in <module>
    import gst
  File "/usr/lib/python2.7/dist-packages/gst-0.10/gst/__init__.py",
line 193, in <module>
    from _gst import *
ImportError: could not import gobject (could not find _PyGObject_API object)
--

2) The failure to import gst highlighted a bug in lazygal (fix: [1])
and I just released 0.8.5 to fix this. But video transcoding still
won't work.

I'm working on porting to Gstreamer >= 1.0 so this will eventually go
away. But I'm a bit stuck in some things segfaulting (grabbing frames
using appsink).
