Expanding foam and inside ceiling condensation cure?

When I moved into my 1880's house it was a damp and condensation nightmare. I had the damp walls insulated with bubble-wrap type insulation under plaster and that solved practically everything. That has been in for 2 years with no problems.

When the work was done, the absolute worst place in the house was a junction of two downstairs outside walls and the corner of the ceiling in the room next to the kitchen. We can't ventilate the kitchen as it does not have an outside wall so I am certain this is the downstairs main condensation point. The work has completely cured the walls and as we thought the ceiling damp was spreading from the walls that it would also cure the ceiling.

Although there is a major improvement (no black mould for instance) the ceiling in the corner has a very slowly growing damp patch. As there is quite a void between the ceiling and the floor upstairs and this is the coldest corner of the house I assume it is the cold air in the void that is drawing the condensation.

To fix this properly I assume I am going to have to have the ceiling down, which I want to avoid. If I drill holes in the damp corner and fill the void with expanding insulation foam, is this likely to solve the problem or am I likely to cause more problems?
