[Pkg-owncloud-maintainers] Bug#761396: owncloud: Backports version should depend on php-sabre-dav >=1.8

[Michael Herold]

Package: owncloud

Dear Maintainers,

I upgraded owncloud to version 7 from backports. Then I got errors that
the class Sabre\DAV\URLUtil is missing. It turned out that php-sabre-dav
1.7 seems to have a different naming convention for classes. Upgrading
to version 1.8.10-1~bpo70+1 from backports resolved the issue.

Sounds like a proper dependency with php-sabre-dav >=1.8 could save
other people from this trouble.

Thanks for all the good work on packaging owncloud!
