Error during site creation because indexing directory does not yet exists.

42 r16833

When I create a new virtal site, I've an error in console, because the indexing directory has not yet been created. The message informs that this directory will be created at first indexation. Wouldn't it be better to create it imediately, so that this error isn't displayed at each site creation?
If this directory's creation is delayed for a good reason, please mask this message, as it seems to be a normal behavior.
