Bug#1022830: apt ignores versioned provides if non-matching version is installed via another dep

[Marc Dequènes (duck) <duck@duckcorp.org>]

Package: apt
Version: 2.5.3+b1
Severity: important
Control: affects -1 redmine


Quack,

I had a weird FTBFS in #1022340 and it looks like the resolver is just 
skipping the versioned dep because another dep provides the same virtual 
package. Unfortunately it does not resolve the required version and 
should install the non-virtual package providing the right version (they 
are co-installable). More info in the referenced BR.

I bumped the severity because I don't see any way to work around this. 
We certainly cannot drop the provides or that would break things. We 
also cannot change the content of the Ruby standard library. Maybe 
redmine does not need the new features in 3.2.0 but since they 
specifically bump the dep I would not bet on that.

Could you have a look please?

Regards.
