Hi,

automatic installation tests of packages that share a file and at the
same time do not conflict by their package dependency relationships has
detected the following problem:

This is a serious bug as it makes installation fail. Possible
solutions are to have the two packages conflict, to rename the common
file in one of the two packages, or to remove the file from one
package and have this package depend on the other package. File
diversions or a Replace relation are another possibility.

Here is a list of files that are known to be shared by both packages
(according to the Contents file for sid/amd64, which may be
slightly out of sync):


  usr/share/php/.registry/xml_util.reg
  usr/share/php/XML/Util.php
  

This bug is assigned to both packages. If you, the maintainers of
the two packages in question, have agreed on which of the packages will
resolve the problem please reassign the bug to that package.

-Ralf.
