It is possible to install a mix of svn packages (in this case
openSUSE:Leap:42.1:Update, devel:tools:scm and devel:tools:scm:1.8) which
passes zypper verify, but renders the package unusable:

subversion-perl-1.9.3-222.2.x86_64
subversion-devel-1.9.3-222.2.x86_64
subversion-tools-1.8.10-6.1.x86_64
subversion-bash-completion-1.9.3-222.2.noarch
subversion-1.9.3-222.2.x86_64
libsvn_auth_kwallet-1-0-1.8.10-6.1.x86_64

$ svn help status
svn: E200019: Version mismatch in 'svn_kwallet' (expecting equality): found
1.8.10, expected 1.9.3

Dependencies need a fix, probably in the devel package.
