We already tried to track them down with your current version but obviously
without success. In the meantime we even made some changes to improve the
session validation and they might already have solved your issue as well.
Either you install the latest SVN in order to verify or we have to provide
patches which you can apply and test again. I just wanted to make sure that
you have a fresh installation without any hacking or patching being done so

I'm sure you need them but we're in the process of finding a bug. Therefore
we first have to locate it and this is the way to do so. I'm not saying
you'll never be able to use these plugins again.

Again, we're trying to track down the problems here and one big factor in a
web service is the browser. Sure, it has to work with IE8 or whatever
browser but with this, I'd like to learn whether there are differences in
session timeouts when using different browsers (from the same machine I
forgot to mention).

That's certainly up to you. But if you want to help investigating this
problem, that's one thing I ask for. We cannot help you if everything is
working fine for us with other browsers or even with IE8 but yours has some
different settings or plugins installed which might cause some weird
behavior. I'm just trying to locate the component which causes your session

I'm sure there'll be another session timeout to be logged :-)
