World of Warcraft Patch 6.1 - New Patch new problem

Again. After update my WoW stopped running. This time there was no WoW-64 to disable, nor libraries to turn off.

When starting WoW without the Launcher like here what I got was an error window telling me:


This application has encountered a critical error:

ERROR #134 (0x85100086) Fatal Condition

Unable to open DBFilesClient\SoundEntriesFallbacks.dbc:

What needs doing is making sure you have actually upgraded the game.
So get into your installation directory and run Launcher

> cd /home/ishtar/.wine/drive_c/Program\ Files\ \(x86\)/World\ of\ Warcraft
> wine World\ of\ Warcraft\ Launcher.exe

And wait for the update to actually happen. If there is no update to be done it may mean your installation is so broken it's best to clean it and let the launcher repair it.
So again go to the installation directory, delete the Cache dir and start the launcher again.
