Hi Tomd

I'm seeing exactly the same issue in my Alfresco 3.4.d instance (x64 Ubuntu server). The one difference is that the "stale" version is always show to some users and never shown to other users - but with regards to the exception you listed from the log it's identical. 

Can I ask did you discover more around the cause / resolve of the issue. I'm tempted to revert to backup, to see if this resolves the issue. FYI I have rebuilt my indexes without success.

Thanks

Gavin.
