integrate 'quotient by zero' error message



I'm guessing  the integrate code finds divide by
   zero here?

The "quotient by zero" error message seems
unclear English.
----------------------

(%i25) integrate(sin(x+sqrt(x))/(1+x),x,0,inf);

`quotient' by `zero'

 -- an error. To debug this try: debugmode(true);

(%i26) integrate(sin(x+sqrt(x))/(1+x),x,0,10);

`quotient' by `zero'

 -- an error. To debug this try: debugmode(true);

(%i27) integrate(sin(x+sqrt(x))/(1+x),x);

`quotient' by `zero'

 -- an error. To debug this try: debugmode(true);
