When trying to reproduce it manually, sending kill -HUP causes syslog-ng

I am able to consistently reproduce this.
No data is written to the new logfile until I manually restart syslog-ng
Could you do it again and in the same time strace-ing the syslog-ng?
(strace -fo output -s 512 -p `pidof syslog-ng`) And after it please send
the output to me.
Thanks.
Sorry about the delay, things have been pretty busy.
Attached is the strace output.
Below is the process I used:
d350-berlin:~# cat /var/run/syslog-ng.pid; echo
24507
d350-berlin:~# kill -HUP `cat /var/run/syslog-ng.pid`
d350-berlin:~# cat /var/run/syslog-ng.pid; echo
24507
d350-berlin:~# ps ax | grep syslog-ng
24551 pts/2S+ 0:00 grep syslog-ng

As you can see, -HUP is causing syslog-ng to die (in fact the strace
says it's segfaulting.. always fun), thus leaving us without any logging
of any kind.
Let me know if you need any more information.
Thanks,
Chris
