@meeseeksdev backport to 1.0.x

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

$ git checkout 1.0.x$ git pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

$ git cherry-pick -m1 8190b83c941ee28e72c9d501522c9c7ae4c26aec

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

$ git commit -am 'Backport PR #7027: restores silent failure behavior when a fileType has no iconClass'

4. Push to a named branch :

git push YOURFORK 1.0.x:auto-backport-of-pr-7027-on-1.0.x

5. Create a PR against branch 1.0.x, I would have named this PR:

"Backport PR#7027 on branch 1.0.x"

And apply the correct labels and milestones.

Congratulation you did some good work ! Hopefully your backport PR will be tested by the continuous integration and merged soon!

If these instruction are inaccurate, feel free tosuggest an improvement.
