Not sure what is meant by 'file isn't added to Openshot ' , but...

1. is it possible to verify that your test machine has the same
characteristics as mine, in terms of 64/32 bit, Python library versions,
etc...

2. is there a way to get this test case tried out on a number of
different machines with different characteristics ??

CPU I am using is:

cat /proc/cpuinfo

3. I have been experimenting with Python debug / analysis tools  ( I am a complete beginner @ Python); by using the command line

 python -m trace --trace  /usr/bin/openshot >python_trc.log 2>&1

I get a trace of every statement executed upto the point where I kill
the process (for some reason, if you pass the name of the input file on
the command line, Openshot does not start..).

Last 1,000 lines of a 600MByte log file are attached; it shows that the code is in a repetitive loop, dependent on things like whether pre-view is paused, and clip length, etc, etc..
      Maybe someone who is practiced in the art of reading Python code can review this, paying special attention to what happens if clip length has 'unexpected values', due to, for example, no clip being 'on the timeline'; or clip has been re-sized...

4. maybe this is really a Python bug...when I kill the process as
started above, then switch back to the non-root console with Ctrl-
Alt-F7, the logged in user session appears to be 'rebooted / re-started'
(you see some process stop/start messages like when the PC boots/shuts
down; then the log-in screen appears)....this does not happen in the the
python -m trace option is not used..

5. NB: I have used the above method twice (first time was not
redirecting the trace output to a log file); 1st time, I had to 'File >
Import' the CIMG.AVI file, BUT 2nd time the AVI file was already
'visible' as a thumbnail... this does NOT happen when the python -m
trace facility is NOT used ...

FWIW, IMHO, there is a race or hazard somewhere, which is why symptoms
vary slightly on my machine, and so far do not appear on your machine.

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

     OpenShot (version 1.4.3)
  --------------------------------
  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.
