This v1.9.1 patch addresses a number of minor problems, class tweaks, UI changes, including a bug that made searching in auction houses to return blank pages.
World of Warcraft Client Patch 1.9.1
General
Various disconnection issues have been fixed.
PvP & Battlegrounds
You should no longer be able to cast Divine Intervention on a flag carrier in Warsong Gulch.
Druid
Heart of the Wild - Previously, when shifting to Bear Form or Dire Bear Form, this talent would cause your current health to increase by the same amount as your max health. Now it will cause your percentage of max health to be the same before and after the shift, as well as shifting back to humanoid form. As a result, shifting in and out of these forms will no longer cause an increase in current health.
Druids with the Symbol of Unending Energy will now be properly awarded 30 energy if their finishing move is dodged, parried, blocked, or missed.
Feral Charge - Should no longer desync characters from the server when charging from land to water.
Priest
Mind Control - Now functions properly. Previously, the person who was charmed did not appear to be moving on their screen or any other local clients.
Warrior
Charge - Should no longer desync characters from the server when charging from land to water.
Items
Elixir of Poison Resistance now removes up to 4 poison effects up to level 60.

User Interface
Using the search feature "Usable Items" no longer causes all pages on the auction house after the first to appear blank.
The warning regarding Full realms should now only appear if you do not have characters on said realm.
Various errors occurring during use of the default user interface have been fixed.
