[xwiki-users] feedback: debian install

Hi, i played a litle bit with the new release 3.4 and debian on virtual machines. First i tried out the standalone installation on the testing distribution wheezy. The installation works well. But the page 'Administration: Rights' does not show the users and the groups. Did not investigate the situation further. Instead tried to install form the debian package xwiki-enterprise-tomcat-pgsql. Here got the error 'depends on libpg-java (>= 8.4) [UNAVAILABLE]'. Should XWiki run on wheezy at all? So I changed to the stable distribution squeeze. The installation of the deb package xwiki-enterprise-tomcat-pgsql works well here (did not try the standalone installation anymore). The Wiki is also runing well, with one exception: The browser shows a message box with the text 'Server returned TRANSPORT_ERROR with no error message' somtimes. But all seems to be ok. So far my feedback. The issues with the testing distribution are no problem for me. Feel confortable enough with the stable distribution but would like to get rid of the above-mentioned errer messages. Any ideas how to solve this. Thanks Ritchi
