Description:
If installing openssh-askpass along with openssh, the latter is not configured to run the former.
File /etc/profile.d/openssh-askpass.sh contains a wrong path:

/usr/lib/openssh/qt4-ssh-askpass

The executable is called placed into /usr/bin instead.

Additional info:
* package version: openssh-askpass-2.0.0-1
* possible fix:

# ln -s /usr/bin/qt4-ssh-askpass /usr/lib/ssh/qt4-ssh-askpass

Replace openssh with ssh in /etc/profile.d/openssh-askpass.sh

Steps to reproduce:
pacman -Rs openssh (and dependencies)
pacman -S openssh openssh-askpass (and dependencies)

try to use a GUI program that relies on ssh authentication, e.g. virt-manager
and you will get an error like:

Unable to connect to libvirt.
You need to install openssh-askpass or similar
to connect to this host.

Why I think it's important to fix this problem: some people may want to replace
x11-ssh-askpass with openssh-askpass because the former does not offer any way
to paste a password from the clipboard. This feature is needed if someone uses
keepassx, password gorilla or similar password safe managers.
