Extremely common for the States. Up until they did "non-stop seasons" the first three seasons of 24 would take a 1-3 week break at about four different points in the season. That's the main reason why so many 20+ episode per season shows in the US will start up between September and November and won't wrap up the season until May.
Shorter TV shows and "summer series" aren't immune to this either. Burn Notice tends to start up in June or July and have about a 16 episode season. There will be a one week break in the first quarter, a TWO TO THREE MONTH break in the middle and finally another one week break at the 3/4 mark before finishing up in December or January. Excluding the first season which was only six episodes it seems like this is the format that AMC's TWD follows (I don't seem to recall any short breaks however :P)
Honestly the only show with no breaks in recent memory that comes to mind is the US remake of Being Human. I can't speak for the first season but unless there was a one week break in the middle that I missed then they wound up doing a 12 episode season with no breaks. Of course the only problem with such a short season is the NINE MONTH WAIT BETWEEN SEASONS :-/
