Is this crack anything to worry about?

Wall is line with door is the main wall of the house.

This is effectively a 2.5 brick wide extension, with a concrete flat roof above. There is therefore no load on the wall above (except for the roof).

There are no other signs of cracking anywhere else in the building. The crack show is approx 5-6mm wide at the top course of bricks. I suspect that the wall hasn't been painted for many years.

Is it just a matter of filling, and seeing it it moves again, or should anything else be done. What is likely to have caused it?

A bit of stress on the corner from the roof slab (as it moved), or knocked when built.

It looks old.

Fill it with mortar and paint over it. It will most likely form another hairline crack, but not a problem

Or use a flexible mastic - not silicone though as it wont take paint

It looks as though there has been a slight shift outwards at the roof abutment, as if the concrete roof itself has expanded slightly. If it is stable then no worries, if there is evidence of re-bar rust then the sooner you get it painted the better.
