Bug#323558: build-dep shows a real package as virtual with two identical canidates
Package: apt
Version: 0.6.40.1
Severity: normal
Hello, in the log below you see that "apt-get install" chooses exactly one
package because only one candidate exists. However, build-dep erraneosly shows
the same package twice as candidate.
