Installing csladspa causes a segmentation fault on ardour (and probably other 
ladspa-enabled programs) (when loading the ladspa plugins, of course). The 
root of the problem is this section from CountCSD (trimmed for clarity):

ladspa_path = getenv("LADSPA_PATH");
path = ladspa_path;

The problem is that if LADSPA_PATH is unset, getenv returns NULL, std::string 
tries to call strlen on that (of course, this depends on the std c++ lib 
implementation), and boom, crash. Safeguarding the path assigning like this 
fixes the issue:

  if(ladspa_path != NULL)
          path = ladspa_path;
