I assume you did this as root or used sudo. You may have to check 
whether you have the proper udev rules in place. See 
http://wireless.kernel.org/en/developers/Regulatory/CRDA#Letting_the_kernel_call_CRDA

I get country US (after iw reg set EU). I tried 'iw reg set ES' after 
that and another message showed up in the log:
[ 1613.052044] cfg80211: Calling CRDA for country: EU
[ 1845.365115] cfg80211: Pending regulatory request, waiting for it to 
be processed...

It seems cfg80211 expects CRDA to respond to the country setting for EU. 
I am not familiar what modules are involved in this usage scenario.
