The bug is fixed in libproxy0 0.3.1-6 (or earlier). The Ubuntu bug
#1038578 is linked to number one VLC crash [1], but I think that link is
wrong. The backtrace of the number one VLC crash has no libproxy in it.
If Ubuntu bug #1038578 was more widespread, it would probably have one
reporter collecting all needed crash information, wouldn't it?

What would we loose when we switch from libproxy to the plain old
$http_proxy? I tend to think that we should just keep libproxy enabled
and wait for the 2.1 release (that will come soon!?). What do you
recommend, Rémi?

@Jules: I don't think that it makes sense to bump the version of a
dependency for every bug in the dependency, unless the bug renders the
package useless for every user.
