Although I have described the latest situation through mails, this is to record
the summary with this bug, so everything remains in one place, for all people to
see.

1. Although you were able to recover the document, I was not even able to open
the document with the same version of OOo (i.e., 2.0.4 Final). My PC is very
powerful (Pentium 4 with HT, 3 GHz, with 1 GB memory, Win XP SP-2). I have
closed all other applications to avoid loading. Even then my attempts failed.

DEFINITELY there is another PC-specific factor here. Could it be the Java
version we use? I am using J2SE 1.5.0_06-b05.)

2. After receiving the modified document, I have selected the ENTIRE document
and reset the "keep with the next paragraph" property of ALL paragraphs. But
even now the document fails often. If I use the Tools> Update> Page formatting,
the repagination progress bar stops and then OOo hangs. The CPU reaches a steady
50% and remains at that level. I have noticed that the progress bar ALWAYS stops
at specific points (either 55% or 20%). I guess that at these points, the
algorithm must be doing something that is prone to "infinite aloop" behavior.

This is another issue that can be investigated.

3. Under no circumstances should an algorithm be allowed to loop endlessly.
There should be a limit on the number of loops: Once that limit is reached, the
algorithm should exit from the loop. Even if the document is NOT fully optimized
at this point, at least the OOo does not hang, and the user can go on working!

Given the choice between losing all work and an odd-looking document, I'd take
the latter.

4. The anchor and image should not be allowed to enter an endless chase. They
should be moved together: Once a author has arranged them in a certain
configuration, Ooo has no reason to change that. 

Specifically, the algorithm has a problem when images are placed in/around
tables, with their anchors placed INSIDE a cell. (I had to do that to stop the
images from drifting away from the text. See issue 60757 for a related problem).

Even here, there should be a loop counter that exits the loop after certain
iterations.
