Now that you mention it, I do recall someone having a similar problem in the Verdistis sewers. They just avoided picking up any poison potions in the sewer.
There were a couple other broken skills (expertise with fixed damage bonuses), that the 1.34 patch fixed. The Larians did say they wanted to release another patch to clear up the outstanding bugs, but since CDV isn't going to pay for it, it is a matter of finding the time to do so. Depending on the amount of work required to fix/test another patch, I would guess it wouldn't be released before Riftrunner is complete. After that... maybe.
