ng-show is not working (angularjs version 1.4.4) when ng-class is having array expression

Here is the plnkr to demonstrate the issue.

In your plunker your controller is not defined, and this is the error message your got in the console

Sorry for the wrong plnkr.

Here is the updated plnkr. http://plnkr.co/edit/qNTsC8sWS7b1u76zvfbO?p=preview

When we remove the ng-class expression every thing work as expected.

In the function addRemoveClassesPostDigest at line 4876, elements are added to the postDigestElements and then the classes are validated.

When the classes to be added or removed are not valid classNames, elements are not removed from the postDigestElements. Because of which function to apply the classes is never registered (line 4903)

I have tried different things in your plnkr, and I was able to reproduce only combining an empty string and a null or undefined in the array. Using only null or only empty string works. If you can avoid mixing both you will by-pass the problem.
The minimum to reproduce is:
ng-class="[null, '']"
(only including angular, no controller, no css, no animate)

I can't do that because the values in my case will be dynamic in nature.

This used to work with angular 1.4.3. Only with angular 1.4.4 we are facing this problem.

Looks like it's caused by 0d6fc2d
Though I'm not sure why the element with ngClass affects the elements with ngShow.
