Bug Description

Xubuntu 9.10
Installing OpenShot 1.0.0 from ppa.
After installing OpenShot, Totem and Exaile stop working. The error from terminal: ERROR: Could not load classifier cascade /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml

I also found a solution how to repair Totem and Exaile:

It is necessary to use these commands:
# sudo apt-get purge frei0r-plugins libcv1 libhighgui1 libcvaux1
# sudo apt-get install libcv1 libhighgui1 libcvaux1

This unfortunatelly unistalls OpenShot. So I can either have installed OpenShot and killed Totem and Exaile or have functional Totem and Exaile but not OpenShot installed.

This issue seems to be related to frei0r-plugins. When I wanted to unistall frei0r-plugins, it will also require to uninstall OpenShot.

You have another solution which will confirm (or not) if freiOr-plugins are the case and will give you the possibilities to use Openshot. The freiOr-plugins are not essentiels for working with Openshot. You have an account launchpad so you can have the main branch by this command :
bzr branch lp:openshot/1.0
After go until the folder openshot (the second) and in a console type :
and enjoy, after you could create a little script and a desktop file.

I tried bzr branch lp:openshot/1.0
cd ~/1.0
python openshot/

Exception in thread Thread-1:

I had to install python-mlt_1.0-3~karmic_i386.deb
Then I was able to start OpenShot by python openshot/
But Exaile failed on the same error as above.So I had to remove python-mlt that also removed frei0r-plugins.
Than Exaile worked.
