I noticed this problem in 9.5. I do not know if this is new issue or not. Will open a ticket on it just in case also. This seems to happen on some output and so far see it from maxima only but could also when using other algorithms. I need to check more. Here is an example
>sage

sage: anti = integrate(1 / (1 + cos(x) ^ 5), x, algorithm="maxima")
sage: latex(anti)

Doing the same, but using "fricas" instead of "maxima" shows no issues and the latex is generated with no problem. This is on Arch Linux running inside Virtual box.
