Exclamation [Q] Dialler force close

When I dial a contact that is found in the directory of Exchange the dailler will force close.

Anybody else notice this? I am using the Exchange directory through work. This worked fine on previous android phones I've had.

Just to add to this it only happens when the number is an internal number i.e. 103. If I type the number in directly then it works fine.
