FWIW:
I do not know the correlation of versions between LO and AOO, but today
I got the following two security reports from the AOO users forum:
-------------------------------------------------------
CVE-2013-2189
OpenOffice DOC Memory Corruption Vulnerability
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected:
Apache OpenOffice 3.4.0 to 3.4.1 on all platforms.
Predecessor versions of OpenOffice.org may be also affected.
Description:
The vulnerability is caused by operating on invalid PLCF (Plex of
Character Positions in File) data when parsing a malformed DOC document
file. Specially crafted documents can be used for denial-of-service
attacks. Further exploits are possible but have not been verified.
Mitigation:
Apache OpenOffice 3.4 users are advised to upgrade to Apache
OpenOffice 4.0. Users who are unable to upgrade immediately should be
cautious when opening untrusted documents.
Credits:
The Apache OpenOffice Security Team credits Jeremy Brown of
Microsoft Vulnerability Research as the discoverer of this flaw.

Could this be related, in that now LO 4.1 rejects such files where LO
4.0 did not?
Just a messenger.

Hi :)
I sometimes get that from files "on the network" but when i copy them to local
desktop machine they work fine. I've not really been tracking which versions it happens
with. There seems to be something about the memory settings as higher spec machines with
memory settings radically bumped right up seem to suffer this a lot less. They still get
it occasionally tho.
I thought it was my inexperience with networking or something
Regard from
Tom :)

Subject: [libreoffice-users] Attempting to open any Microsoft XML document
causes General I/O error after upgrade to 4.1
Just wanted to check here before I go open a bug...
I just upgraded to 4.1, everything seemed fine, but I encountered a
.docx document this morning, and got the dreaded 'General I/O' error.
I then tried a bunch of different XML documents (.docx, .xslx, and
.pptx), and every one resulted in the same error.
These are all docs that opened fine in 4.0.4
Will go back to 4.0.4 and confirm it resolves the problem...
