Title:
  OpenShot hangs in an infinite loop when exporting

  New

Bug description:
  I created a new project with 2 tracks. On one track there is an OGG

  The export seems to finish in a reasonaly time, but then OpenShot
  continues to use 100% CPU and the export dialog

  This is OpenShot 1.4.0-1 (Ubuntu 11.10 package) on a 64-bit Intel

  I used the DVD-PAL export profile.
