That's not really a bug, it's just obtuse. I'd recommend to Bioware that a map marker at the requisition table in the base camp would really clarify where to go.
A missing quest marker is no bug?
But thank you. Requisition table... I allways went to the war table ^^
PS.:
IMHO Another bug
Before you are able to activate the trail which opens the icy gate you need to turn on two engines with runes and pull a lever.
After activating the glyphs the task is to look around for clues BUT the quest marker is still set up in this room.
The lever is outside. The questmarker should be exchanged through a quest area. The ones indicating that there is something somehere around.
The marker is very irritating because it is inside and there is nothing to be found in there.
PPS.:
This quest is buggy, too.

I did not find any artifacts/skulls in the swamps first.
What I did was: having a veil fire lit as I visited the women who is preparing a corpse.
I found the glyphs, read them and the quest was triggered.
Afterwards I was asked to see the augur, which I did. The part with the glyphes was solved now BUT this is not the complete quest. It remained active but there was no second subentry to look for the skulls.
If it was not for the How To on the URL above I would not have known what to do.
Furthermore there should be some runes in the Augur's hut. There have been none.
