OK this part is reproducible and may not be the real problem. In this case the 
logrotate causes dnsmasq to not write to the new dnsmasq.log file. It writes to 
the old file (dnsmasq.log-20130213). The logs indicate that SIGHUP indeed is 
processed.

There is a bug in our logrotate config
postrotate
        [ ! -f /var/run/dnsmasq.pid ] || kill -USR2 `cat /var/run/dnsmasq.pid`

should be
postrotate
        [ ! -f /var/run/dnsmasq.pid ] || kill -USR2 `cat 
/var/run/dnsmasq/dnsmasq.pid`
