I have a presentation which, when edited in Impress 1.1rc3 under either Windows
2000 _or_ RH 9 (2.4.22), eventually cannot be saved.  Saving fails with "General
input/output error" in both cases.

I would be happy to send the presentation to someone who debugs such things, but
it contains company-confidential information.  If there is some set of actions I
can take to diagnose this, such as running OO under gdb or compiling a version
that logs debugging information to a file, I'd be delighted to do so.

Incidentally, the following things work when I get into this situation:
a) create a new presentation, copy all slides into the new presentation, and
save that immediately.
b) generate PDF output
c) save as PPT (to the extent that saving any presentation as powerpoint works).

If I do (a) above, I can edit that presentation for a while before I get into
this error situation again.  The presentation is large (2.3 MB) but not terribly so.

Here are some things that don't work:
a) rename file, return to Impress and try to save to original filename again
b) save under a different name but still in sxi format
c) quit other applications and try again

Thanks.
