+Subject: [PATCH] BUGFIX: fix "Floating point exception" in
+ tcplog_flowrate_msg()
+
+commit 0d55bee "tcplog_flowrate_msg(): cleanup and fix") removed
+condition, which leads to zero division.
+
+Time diff between current time and ->conn_starttime is 0, because of
+rate_print updates happen in less then 1 sec and later on, we try to
+divide ->bcount by interval, which is 0, hencs zero division.
