The main reason to worry is, largely, one of personality. The Times runs a quote to the effect that Gereral Ashfaq Kayani is behind the decision to cancel the intelligence trip, and that he has been “angered” by Cameron.

He is said to working ceaselessly towards a Pakistan-friendly regime in Kabul, and that goal most likely involves making concessions to the Taliban. Anything which pushes him further away from the West, and closer to the West’s enemies, could make those concessions even greater.
