Morning Alan
If you look back at his other thread I suggested renovating plaster as a proper modern alternative which is far superior to any sand and cement job. The crack can only be appearing due to application or mix as I said before. I would hack a bit of the wall off where it is cracking to make sure it does have a proper hold of the brickwowork as like I said earlier as well the bricks are low suction and the fact they have had plaster on them before make them have even less suction.
And derader is right Im not here to gloat just explain possible causes as its only the plastered who can put it right and to determine how bad the cracks are from a couple of pictures is really hard but what you can see is that they are really bad to show up on camera like that!
