OK, after adding the line

  deb http://debug.mirrors.debian.org/debian-debug/ testing-debug main

to my /etc/apt/sources.list, and after installing the following debug
symbol packages:

  # aptitude install pitivi-dbgsym \
 libglib2.0-0-dbgsym \
 libgstreamer1.0-0-dbg \
 gstreamer1.0-plugins-base-dbg \
 gstreamer1.0-plugins-good-dbg \
 gstreamer1.0-plugins-bad-dbg

I started pitivi inside gdb:

  $ gdb python3 -ex "run $(which pitivi)"

And I followed the steps described in my original bug report.

After seeing pitivi frozen, I hit [Ctrl+Z]:

  Thread 1 "pitivi" received signal SIGTSTP, Stopped (user).

A stacktrace would be useful. Also if you could upload the file somewhere
where we can get it.

What happens is that pitivi stops responding (again) and I see the
following error messages on stdout or stderr:

  Missing soft dependency:
  - GSound not found on the system
  -> enables sound notifications when rendering is complete

It seems that I cannot play the file with gst-play-1.0 either:

  $ gst-play-1.0 file.ogg
  Press 'k' to see a list of keyboard shortcuts.
  Now playing /home/.../file.ogg
  Prerolling...

and then nothing happens, until I hit [Ctrl+C].

I can try to get a stack trace.

Do you need a stack trace of pitivi?
Or, since gst-play-1.0 is also hanging, do you prefer a stack trace of
gst-play-1.0 ?

Please let me know, thanks.

Bug#898379: pitivi: no longer responds as soon as I try to import an Ogg Vorbis audio file

2018-05-13 Thread Alexandru Băluț 
There might be a problem reading those files. When you click Import and the
import window opens, please select the ogg file and tell us what happens
when you click "play" on the right side under the small preview.

Can you play those files with GStreamer from the command line? Try:
gst-play-1.0 PATH-TO-OGG-FILE

Please see
http://developer.pitivi.org/Bug_reporting.html?stack-traces-for-crashes-and-deadlocks
for how to provide a stack trace when Pitivi hangs.

Bug#898379: pitivi: no longer responds as soon as I try to import an Ogg Vorbis audio file

2018-05-10 Thread Francesco Poli (wintermute) 
Package: pitivi
Version: 0.99-3
Severity: important

Hello!
Thanks for maintaining pitivi in Debian.

I am trying to learn how to use it, but I am experiencing an
important bug.
Steps to reproduce the issue:

  0) start pitivi

 $ pitivi

  1) click on the New button in the welcome dialog window

  2) click on the Import button in the media library tab

  3) go to a directory where one or more Ogg Vorbis files are
 present

  4) select one .ogg file and click on the Add button

  5) pitivi stops responding, its windows are no longer repainted,
 and there's nothing I can do, apart from killing the process...

I have tried a number of .ogg files, without any success.
In some cases I get the following errors:

  ERROR 00:03:38 assetpipeline  
_async_done_not_received_cb: we didn't get async done, this is a bug 
(../../../../usr/lib/x86_64-linux-gnu/pitivi/python/pitivi/utils/pipeline.py:299)
  ERROR 00:03:38 assetpipeline  _recover: 
Pipeline error detected during playback, resetting -- num tries: 0 
(../../../../usr/lib/x86_64-linux-gnu/pitivi/python/pitivi/utils/pipeline.py:469)

but not always.

Is there anything I failed to understand?
Could you please investigate this bug and/or forward my bug report
upstream, as appropriate?

Thanks for your time.
Bye.
