To be sure, i remember of programming like this:

"If the player have not enough inventory space, the quest is unable to be completed, and will tell you to cleanup X inventory spaces."

But i guess it's bugged...

Well, the solution is, sell your stuffs on other npc than the wizard(since the quest will auto complete if you talk to him), then, talk to him after selling these stuffs.

By the way, backup your character before doing it.
