Bug#746686: libwww-perl (+ libio-socket-ip-perl): unhelpful error message for certification verification failure

[Jakub Wilk]

Package: libwww-perl
Version: 6.06-1
Severity: minor

I get a quite unhelpful error message when server certificate 
verification fails:

$ GET https://www.berlios.de/
Can't connect to www.berlios.de:443


Curiously enough, the problem goes away if I uninstall 
libio-socket-ip-perl:

$ sudo dpkg -P libio-socket-ip-perl
(Reading database ... 11620 files and directories currently installed.)
Removing libio-socket-ip-perl ...

$ GET https://www.berlios.de/
Can't connect to www.berlios.de:443 (certificate verify failed)

LWP::Protocol::https::Socket: SSL connect attempt failed with unknown error error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed at /usr/share/perl5/LWP/Protocol/http.pm line 51.
