Take over an ITP in absence of an answer from the bug owner

[Julien Valroff <julien@kirya.net>]

Hi,

I am very interested in taking over fast-user-switch-applet package
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=304763)

I don't own the ITP which is almost one year old, and the owner hasn't
(yet) answered my e-mail.

Now I am wondering what to do if after a few other weeks/messages I get
no answer.

Thanks in advance for your advice!

Cheers,
Julien
