   Yep, it is a second minus that is the problem.   
      
   I also does not like removal of 1/5   
      
   integrate(x/(x^2 - 2*sqrt(-1)/5)/sqrt(x^3 - x),x);   
      
   That again causes catdef: division by zero if   
   you do it 2 times very fast (and I mean VERY).   
   That still requires setSimplifyDenomsFlag(true).
