OK;  procedure to replicate this UI lock-up is now very easy and I think
proves it is not related to input file format:

Start Openshot from command line using

openshot test_file &

IMMEDIATELY press 'Preview play' button (even though the clip thumbnail
has not been dropped onto the timeline).

The 'slider button' jumps almost immediately to right hand end of
travel; depending on whether mouse is still hovering over the Play/Pause
button you may see the Play/Pause legend flash briefly.

MOST of the time, from this point on, 'Desktop / UI' lock up is as
described earlier; on one occasion so far I have been able to re-wind
using the 'seek to start' button a couple of times, but then produced
the lock-up as described by dropping the clip on the timeline, and
shortenning the clip using the Resize tool.

Using Ctrl-Alt-F2 to open a  root console window, you can see about 8%
of CPU is used, AND I think a gradually increasing amount of memory
(will leave it running a while to check).

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
  charlie@fiona-ubuLenovo-3000-G530:~$ 
  ------------------------- ERROR 1 ------------------------------
  Failed to import 'from openshot import main'
  Error Message: cannot import name main

  Process no longer exists: 5295.  Creating new pid lock file.
  Adding files to the watch queue:
  /home/charlie/Pictures/100CASIO/CIMG1113.AVI

  Detecting formats, codecs, and filters...

  etc... 

  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.
