--- Comment #41 from Joe Smith <[email protected]> ---
I have an alternative scenario to demonstrate the problem--the symptoms of the
problem at least.

What I've done is to configure OO to use a temp file location that has limited
space:
The open document (33 embedded images) occupies about 30Mb in temp files
The limited temp area has ~15-20Mb available

There's enough temp space for the main document components but not enough for
all the images. In this situation, OO appears to open the document cleanly,
except that some of the images have the "Read error" place holder. If I try to
save the document in this state (no more temp space), I get "General i/o error
... Can't save subdocument content.xml". If I then free up some temp space and
save again, no error occurs and the resulting file has simply lost some of the
images.

I expect that running out of disk space is unlikely to happen for current
systems with large disks. But even if this is not the actual cause of the
problem, I think this does demonstrate a flaw in the design of OO, that a
serious, document-damaging error is not brought to the user's attention,
allowing the document to be permanently damaged.

I believe this could be related to the image caching: it seems that OO may not
effectively deal with errors in managing the cached files.

Errors in unpacking any part of the document archive (write error: no space in
this situation) should be fatal errors--the document should not open.
