Thanks for the reference to the ppa for latest MLT version; have
installed that, see below for detail.

IF Openshot is started in the back-ground with &, behaviour is as
described earlier.

Tried starting Openshot as the foreground process, FOR ONE OUT OF 2
TRIALS then only the 'video seek' controls are frozen; was able to
minimize the Openshot window, bring a terminal window to the foreground,
and check process state.

Need to repeat this trial a few times (takes time), trying to ensure
that exactly the same set of key press / commands / clicks etc is used
each time to eliminate variation in them as a cause.

Here are last few lines printed by Openshot (started as foreground, the
1 time it did not completely freeze) as I re-sized the clip and tried to
preview, then escaped the 'lock-up': (NOTE, I have not defined a project
for these trials).

legend that is 'stuck' in the middle of the screen: see attached
screenshot.

Title:
  previewing effect of video edits causes Openshot + Desktop to freeze

Status in OpenShot Video Editor:
  Incomplete

Bug description:
  Openshot 1.4.3 installed via PPA under Ubuntu 11.10 as per guide on
  Openshot website.

  Initial messages on start-up:

  charlie@fiona-ubuLenovo-3000-G530:~$ openshot ./Pictures/100CASIO/CIMG1113.AVI &[1] 5498

  application seems to load / run.

  Use the Resize tool to shorten the AVI file loaded above (size is
  approx 13MBytes, generated by a Casio ZX-60 camera); resizing is
  successful and modified AVI file can be saved as mp4, replayed with eg
  Movie.

  BUT: if I use the 'preview' button to check result of the re-size
  before  saving/exporting the video file, the Openshot GUI locks up.

  Moving mouse to left of screen to 'activate' 'Dash' launcher has no
  effect; Alt-Tab has no effect (there are other apps running).

  Ctrl-Alt-F2 DOES bring up a console where root can login;
  Python/Openshot are NOT taking an excessive amount of CPU (virtually
  none..).

  kill -9 'pid of Openshot' restores normal system function.
