I have just deployed reversion 138 and 139 to LaunchPad:
http://bazaar.launchpad.net/~jonoomph/openshot/main/changes<http://bazaar.launchpad.net/%7Ejonoomph/openshot/main/changes>

To save everyone time, here are the commit messages.  If you find these
commit messages terribly confusing, please let me know and I can try and
explain. =)

*Rev 138*
--------------------------------------
Fixed the bug where OpenShot crashes when a non-media file is imported.
Dan helped me fix this one.  We needed to call mlt.Factory.init() each
time we thumbnail a file.  Then we can use the is_valid() method.  So,
now OpenShot just ignores invalid files, and it won't crash & seg fault!

Added in a new "lock" class, that ensures that only 1 instance
of OpenShot can be run at a time.  This has the following features:

 1) Running OpenShot with no command line args (i.e. $ openshot),
    everything works like normal (the 1st instance of OpenShot to be run
    will become the "primary instance".
 2) If you right click on files in Nautilus and open with "openshot",
    it will pass each file to the primary instance of OpenShot... and
    the files will appear in the project tree.  This will not create
    multiple instances of OpenShot

NOTE: You can run multiple version of OpenShot if you don't pass args to
    the command.

3) If you pass args to $ openshot "file path 1", "file path 2", "etc", it
   will add each file to the primary instance of OpenShot

4) If you just run "$ openshot" over and over again, it will continue to
   create new instances of OpenShot, so you could work on multiple projects
   at the same time.  It's only when args are passed along with the
   "openshot" command that this lock stuff is used.

As part of this new "1 instance" code, there is a new /queue/ folder.  A
"queue_watcher" thread polls the files in this folder, and when it finds any
file (text files), it cracks them open, reads the path of a file to import,
imports the file, and then deletes the text file.  The name of the text
file does not matter.

For example, if you manually create the following files in the /queue/
folder:

abc123.txt (and it contains:  /home/jonathan/my_video_1.avi)
def456.txt (and it contains:  /home/jonathan/my_video_2.avi)

The queue_watcher thread should almost instantly delete these 2 text files,
and then import the 2 files into the primary instance of OpenShot.
This creates an interesting interface for people to work with, if
they want to script with OpenShot.

*Rev 139*
--------------------------------------
MLT needs to have the Factory re-inited each time we load a
producer, otherwise it seems less stable... and more likely
to seg fault.

bumping version to 0.9.25
