I think the error is triggered by an actual bug in "rationalize"
somewhere, so it might be worth reporting the error upstream. There is
no reason why "replace a float by a nearby rational number" should
ever fail.
Workaround:
sage: integrate(f(1.5,1,t), (t,0,2*pi))
sage: M=sage.calculus.calculus.maxima
sage: M.eval("keepfloat: false;")
'false'
sage: integrate(f(1.5,1,t), (t,0,2*pi))
-2*pi
sage: M.eval("keepfloat: true;") # this is the default
'true'
sage: integrate(f(1.5,1,t), (t,0,2*pi))
RuntimeError
