Hello, 

Doing: 
$ /usr/bin/httrack --disable-security-limits --max-rate=0  -%c3000 --continue
-s0 urlofgooglehere

results in:
Floating point exception (core dumped)

with the latest svn revision. 

Running the distribution version, it returns: Segmentation fault (core
dumped). 

In short, there appear to be no versions of httrack around that behave
properly.
