Problem with VM 2.0.12f and expires header if VM Frontpage is Joomla start page

[franzpeter]

There must be a bug in the VM default frontpage. VM does not allow the use of expires headers there. It works with all other Joomla pages and the other virtuemart pages but not with Virtuemart front page as start page. Meanwhile VM Frontpage (as start page), which is a link in the Joomla menu and defined as start page, does not read the meta tags from the menu link. So without using Joomla global meta tags there are no meta tags if the Joomla start page is defined as virtuemart front page.
The first mentioned bug is a performance problem, the second one will provoke bad page ranks in search engines.
