Hi,
If you could post the packet it might be trivial to fix "proper" decoding.

The basic problem is that de_bearer_cap() is declared as static in 
packet-gsm_a_dtap.c: that means no other module (.c file) can use it. 
If you remove the keyword "static" it will at least link.  (Of course it 
would also be better to have a prototype in a header file, etc.)
