Bug#244316: dpkg-shlibdeps: locales should be set to C when launching dpkg --search

[Cédric Delfosse <cedric@debian.org>]

Package: dpkg-dev
Version: 1.10.20
Severity: normal

In /usr/bin/dpkg-shlibdeps, line 197:

    while (<P>) {
       chomp;
       if (m/^local diversion |^diversion by/) {
           &warn("diversions involved - output may be incorrect");
           print(STDERR " $_\n") || syserr("write diversion info to stderr");
       } elsif (m=^(\S+(, \S+)*): (\S+)$=) {
           push @{$pathpackages{$+}}, split(/, /, $1);
       } else {
           &warn("unknown output from dpkg --search: \`$_'");
       }
    }
 
dpkg messages are localized, so dpkg should be launch with locales set to C.

With French locales for examples, you can see the problem:
dh_shlibdeps
dpkg-shlibdeps: warning: unknown output from dpkg --search: `détourné par nvidia-glx de: /usr/lib/libGL.so.1'
dpkg-shlibdeps: warning: unknown output from dpkg --search: `détourné par nvidia-glx à: /usr/lib/nvidia/libGL.so.1.xlibmesa'

("détourné par" means "diversion by")
