Rogue Helms for bad skin IDs
Thanks for this info. It should be quite helpful for ANet’s bug crew when they get around to it.

In the meantime, if you are desperately trying to unlock the Rogue Mask skin, I know for a fact that the karma helm bought from Magister Kathryn in Dredgehaunt Cliffs (she’s at Tribulation Rift) works for unlocking the skin.
Bumping this, I just started a new thread about this issue because I didn’t realize this one existed since it’s several months old. Saw this linked in another thread about Koss on Koss/Book of Secrets. Will try to either delete my post or have it reference back to this one since this list is more complete than mine.
I surveyed a grand portion of the items available from Karma Vendors across the game and I’ve found that there are a lot of medium head armor items that show the Rogue Helm icon but no skin. Apparently this is due to them pointing to bad skin IDs. The API quotes them as errors.
So if you’ve been wondering why Rogue Helm and any other item that doesn’t reveal what skin it is won’t unlock for you, there’s an answer.
I’ve reviewed the API for the following items/skins and marked which ones appear to be updated.
Fixed:
SKIN 881 -> all of these now points to skin 941, aka Rogue Mask
4173 Oldgate Leather Mask 
4187	Redreave Leather Mask
4244	Bloodsaw Leather Work Mask
4681	Scout’s Mask
4684	Improved Scout’s Mask
4940	Brackwater Mask
4960	Brackwater Mask
Unchanged:
SKIN 1763 -> still points to 1763, which remains invalid
5651	Stalker Boots
SKIN 2009 -> still points to 2009, which remains invalid
6274	Studded Leather Bracers
6394	Stalwart’s Bracers
SKIN 1570 -> still points to 1570, which remains invalid
6305	Chainmail Helm
SKIN 1763 -> still points to 1763, which remains invalid
6419	Mending Boots
SKIN 2318 -> still points to 2318, which remains invalid
37005	Symon’s History of Ascalon
37014	Symon’s History of Ascalon (Infused)

Koss on Koss appears fine. Book of Secrets does not, per the OP by Sariel.
Here are the API links for Koss on Koss
Skin 2376 points to 2376 ->
37001 Koss on Koss   points to 2376 which is valid
37010 Koss on Koss (infused) also points to 2376.
Just checked those skins ingame. All Rogue Masks are fixed.
I will also post a new thread with tons of Wardrobe Bugs soon

You can copy/paste the list of “unchanged” above, assuming you don’t already have it covered (pardon the pun).
