Checkgmail doesn't work with perl 5.12 from testing

[Guillaume Brunerie <guillaume.brunerie@xxxxxxxxx>]

Hi,
Since the update of perl 5.10 to 5.12 yesterday, checkgmail (from community)
doesn’t work anymore, it fails with this error :
   /usr/bin/perl: symbol lookup error:
/usr/lib/perl5/vendor_perl/auto/Glib/Glib.so: undefined symbol:
Perl_sv_utf8_upgrade_flags
Downgrading to perl 5.10 make it work, and updating checkgmail (with
checkgmail --update) doesn’t solve the problem.
I didn’t found anything about this problem in Flyspray or in the forums.

Thank you,

Guillaume Brunerie
