I'll look at that when I'm back from holidays, but note that : 1) there are many different flavours of difference logic and 2) difference logic is really restrictive: for instance, difference logic forbids any use of the addition, according to the spec, and lastly 3) it is known that especially for difference logic, the benchmarks from the smtlib are not all conforming to the spec.

Ok, so I had some free time, here's a response.
QF_IDL/bcnscheduling
There is no error here: as one can read in the spec, addition is not allowed to appear in atoms (which is reasonable given the name "difference" logic). That being said, the error message could be clearer/more explicit, I'll work on that.
Lastly, these benchmarks, while not conforming to the standard spec, actually respect the spirit of the spec: indeed, if one substitutes the let-bound variables and performs some arithmetic simplification/re-ordering of terms, then the benchmark only contains subtractions and no additions, which is why solvers do not complain about them, however it's outside the scope of dolmen to perform such computations currently.
UFIDL problems
Here, indeed as you point out, the error message is the wrong one (but the problems are nonetheless not spec-conforming). I'll fix that asap.
