TYPO3 Core

This is the same bug as described in issue 0000227. I could not reopen it, thus this report. In the Filelist module, as admin I create some file. The absolut path of the file on the machine is /var/lib/typo3-dummy/fileadmin/somefile and I can see the file is in place. I click on the file in fileadmin and the browser gives me the 404 error, that it couldnt find http://localhost/fileadmin/somefile. If I add the missing part of the path "typo3" , I get http://localhost/typo3/fileadmin/somefile and it works.

This is the environment:
Ubuntu 8.10 with LAMP installed:
apache 2.2.9
php 5.2.6
typo3-dummy 4.2.1
typo3-src 4.2.1
typo3-dummy is installed in /var/lib/typo3-dummy
typo3-src ist installed in /usr/share/typo3
apache configuration for typo3: Alias /typo3 /var/lib/typo3-dummy
