On my system, Mathematica 10.1.0 under Windows, none of these FrameTicks documentation examples work correctly:
(* Draw frame ticks at the specified positions with the specific labels: *) Plot[Sin[x], {x, 0, 10}, Frame -> True, FrameTicks -> {{{0, 0 °}, {Pi, 180 °}, {2 Pi, 360 °}, {3 Pi, 540 °}}, {-1/2, 1/2}}] (* Specify frame ticks with scaled lengths: *) Plot[Cos[x], {x, 0, 10}, Frame -> True, FrameTicks -> {{{Pi, 180 °, {.4, .05}, Red}, {2 Pi, 360 °, {.4, .05}, Thick}, {3 Pi, 540 °, {.4, .05}, Directive[Red, Dashed]}}, {-1, 1}}] (* Specify frame ticks with scaled lengths in positive and negative directions: *) Plot[Cos[x], {x, 0, 10}, Frame -> True, FrameTicks -> {{{0, 0 °, {.4, .05}}, {Pi, 180 °, {.4, .05}}, {2 Pi, 360 °, {.4, .05}}, {3 Pi, 540 °, {.4, 0.05}}}, {-1/2, 1/2}}] (* Specify the style of each frame tick: *) Plot[Cos[x], {x, 0, 10}, Frame -> True, FrameTicks -> {{{Pi, 180 °, {.4, .05}, Red}, {2 Pi, 360 °, {.4, .05}, Thick}, {3 Pi, 540 °, {.4, .05}, Directive[Red, Dashed]}}, {-1, 1}}] All produce a pink error box with a Tooltip message

Is this indeed a bug or have a broken something in my configuration?
Does it affect other versions and platforms or only 10.1.0 under Windows?
