bb-histlog.sh : internal server error - SIGSEGV

[Gianluca Rossi <gianluca.rossi (at) acantho.com>]

Hi,
my xymon server (64 bit debian lenny) running Xymon 4.3.0-0.beta2
is sometimes reporting "Internal server error" executing history with 
bb-histolog.sh.

example, this url:
/hobbit-cgi/bb-histlog.sh?HOST=nb-ser&SERVICE=backup&TIMEBUF=Sun_Oct_25_14:39:38_2009

i have the gdb trace:

Program received signal SIGSEGV, Segmentation fault.

there is a problem only for some request, usually the history program 
works fine.
is 4.3.0-0.beta2 the last 4.3 branch? i see on http://www.xymon.com 
Xymon 4.3.0-1.3: is this an updated version?
