Hi,

Just a thought : not sure that WebM  use one channel.

Another thing more concrete : you seem to use an old (and knew as a
buggy version) of MLT. Could you update it following this FAQ :
https://answers.launchpad.net/openshot/+faq/1861

If you want the last version of MLT, you should use this PPA : https://launchpad.net/~sunab/+archive/kdenlive-svn
but be careful, it is a daily PPA so he can break your installation.

After that, try again.
Thxs.

Title:
  Crash exporting WEBM with one audio channel

Status in OpenShot Video Editor:
  New

Bug description:
  Ubuntu 12.04.1 LTS
  OpenShot 1.4.3 installed by PPA
  Melt 0.7.6+git20120

  Principal input clip is an Ogg Theora file about which avprobe says
  that it is 1120x736 with one audio channel: Vorbus, 22050 Hz, mono,
  s16.

  I want to export with the same audio characteristics.

  Export settings:

  Target: WEBM (vpx)
  Video Profile: 1120x736 (aspect ratio 4:3, frame rate 15, pixel ratio 1:1, progressive)
  Quality: Med

  Advanced -- audio settings: 
   sample rate 22050
    # of channels 1
    bit rate 128 kb/s

  Soon after export begins, OpenShot crashes with these messages (some
  might have been from before the export started):

  on_frmMain_key_press_event
  on_mnuAbout_activate called with self.GtkImageMenuItem
  on_aboutdialog1_close called with self.OpenShot

  If I change # of channels to 2, and otherwise the same as above, it
  exports with no problem.
