Thank you for taking the time to report this bug and helping to make Ubuntu better.
I was unable to reproduce this using 2.2.22-1ubuntu1.2 - neither on mpm-prefork, nor mpm-worker, nor mpm-itk.
A difference that might be relevant is that I tried it on a virtual machine with a -virtual 3.2.0-23 kernel, as opposed to -generic.
It appears that this particular VM won't boot with a -generic kernel, so I can't easily go further right now.
