Conceptually, there are two kinds of rdbs, those for types and those for 
services.  For types, LibO itself uses a types.rdb in the URE layer (for 
the general URE types) and an offapi.rdb in the basis layer (for the 
office-suite-specific types).  For services, LibO similarly uses a 
services.rdb in the URE layer and one in the basis layer.

"Binary URP bridge disposed during call" indeed hints at broken 
plumbing, like the two ends of the bridge using different type 
descriptions (which appears unlikely if you use the offapi.rdb from 
LibO's basis layer---together with the types.rdb from LibO's URE layer) 
or something like that.

The easiest would be if you presented a (stripped down) version of your 
failing code.  It might be that you fail to include the URE's types.rdb, 
for example.
