Dolphin won't dump textures

[vladik4kides]

Hey! Dolphin doesn't dump textures!
Checkbox in settings is ticked and folder with title id in Dolphin Emulator\Dump\ is created.
I see how the folder update date is changing and the game fps is slow like it's supposed to dump textures.
But anyways the folder is empty.
I'm using Dolphin 3.0 (stable version from downloads page).
Can someon help me with that?
