Yes, it is.

I have just tried latest firmware from git, it is still not working as 
expected. Ubuntu 13.04 comes by default with FW v1.3, I can confirm that 
I really used the new one, as now the kernel tells me it is FW v1.4 
(before it was 1.3).

Should I open an issue ticket on open-ath9k-htc-firmware? How can I make 
sure where the problem comes from?
