Developers of Sympa

[Olivier Salaün <address@concealed>]

Hi Guillaume,

We'll perform some tests with Perl 5.10 ourselves. Could you please 
submit an "official" bug report in our tracking system : 
https://sourcesup.cru.fr/tracker/?group_id=23

In the meanwhile I recommend you downgrade to perl 5.8.
