Hm, that's rather odd.

For one, this crash is during "clean" termination of the soffice.bin 
process, i.e., at a time when your external code should no longer 
communicate with the soffice.bin process anyway.  (Or is your external 
code designed in a way that it might call 
com.sun.star.frame.XDesktop.terminate while some printing activity is 
still in progress?)

For another, I see no way how 
com::sun::star::ucb::UniversalContentBroker::create could throw an 
exception there during shutdown.  It should already have been called 
during initialization, from Desktop::Main -> Desktop::RegisterServices 
-> configureUcb, and if that had already failed with an exception, that 
would have caused a call to FatalError, which immediately terminates the 
process via _exit.

Are you sure that that crash dump correlates to a "Binary URP bridge 
disposed during call" exception in your client, or could it be from a 
"harmless" crash of an soffice.bin instance after your client code had 
already disconnected (so might normally go rather unnoticed, except for 
leaving behind a crash dump)?
