[Aptitude-devel] Bug#786719: aptitude: cannot forbid a version for a package going to be installed

[Yann Dirson]

Package: aptitude
Version: 0.6.11-1+b1
Severity: normal

Context: iceweasel just got updated in testing from 31 to 38, and that
new version pulls gstreamer1.0-libav.  On upgrade, the apt-listbugs
hook shows the latter as impacted by a serious bug, so as usual for
this situation, I stop the upgrade process and try to forbid that
version of gstreamer1.0-libav.

But the problem is, nothing happens when I use the "F" key.
