php-kolabformat_0.8.1-2_i386.deb - Wrong dependency: phpapi-20100525 instead of phpapi-20100525+lfs

The subject says it all, but here is the context:
  - Virtualbox new virtual machine with basic Debian Wheezy installed
  - /etc/apt/sources.list.d/kolab-3.0.list
       deb http://mirror.kolabsys.com/pub/debian/kolab-3.0/ wheezy release 
updates updates-testing development
      deb-src http://mirror.kolabsys.com/pub/debian/kolab-3.0/ wheezy release 
updates updates-testing development
   - kolabsys repo priority 501

The installation of the whole kolab suite:
   aptitude install kolab
fails with 
   ....
   The following packages have unmet dependencies:
      php-kolabformat : Depends: phpapi-20100525 which is a virtual package.

The right name of the virtual package should be phpapi-20100525+lfs
   http://packages.debian.org/wheezy/phpapi-20100525+lfs

Modifying the dependency in the Debian/control file in a locally crafted php-
kolabformat_0.8.1-2_i386.deb, and fiddling with dpkg -i and apt-get install -f, 
I was able to complete the install of kolab meta package (Filename: 
pool/development/k/kolab/kolab_3.0.0-9_all.deb)

Now going on to test (never used kolab before).
