Looking at the code, tl->options.tooltip is initialized to NULL, which
should crash Solaris 9 out of 9 times.
 
replace line 167 of triggerlauncher.c with this one, and see what
happens:
g_snprintf(caption, sizeof(caption), "%s:
%s",(tl->options.tooltip)?tl->options.tooltip:" ", s);

If it still crashes, do a backtrace to see where else printf is getting
a NULL string.
