Makabi, they disappear for good if you don't play version 1.0034 and put them on the ground - and they disappear if you steal Penumbra's dagger and have these lockpicks in your inventory - but in this case they're IN the guard house desk again, in all versions.

About disappearing stuff in general: When you're encumbered this might happen (weight bug).
