[Pkg-roundcube-maintainers] Bug#785333: broken contextmenu due to jquery

[Kurt Fitzner]

The old jquery linked to in RoundCube also breaks plugins like contextmenu.

The better fix for Debian's RoundCube is not to update the jquery
package to its new upstream, but to include with RoundCube the
appropriate version of jquery supplied from its own upstream.  jquery,
like tinymce, is simply not appropriate as a shared resource.  Web
applications of various ages depend on mutually incompatible versions.

Far too much thought is being put into a very simple problem.  Namely
that too many of the included files from the upstream RoundCube
distribution are being removed from the distribution in favour of
inappropriately trying to link against a common system version.  There
is no advantage to the current approach and it is keeping Debian's
RoundCube packages broken for far too long.
