Comment 8 for bug 430333

I don't know exactly where the problem is right now so I'm unable to
advise on what limits are relevant. Indeed, it might not even be a limit
at all, but some other thing that didn't turn up in my tests ...

While I respect that you might need the computer to work, it's actually
a shame that you're getting rid of the evidence of this problem before
we have a chance to debug it properly. :-( If you can still reproduce
it, perhaps you could hop onto #ubuntu-installer on irc.freenode.net at
some time during European working hours and I may be able to have a look
at it with you?
