apt-listbugs error

[Gerard Robin <g.robin3@free.fr>]

Hello,
apt-listbugs works fine for almost all packages except for
texlive-latex-base: (for me)

sudo apt-listbugs list texlive-latex-base:

Retrieving bug reports... 0% Fail
Error retrieving bug reports from the server with the following error message:
 W: invalid date
It could be because your network is down, or because of broken proxy servers, or 
the BTS server itself is down. Check network configuration and try again


Does someone knows what happen ?
