The problem has to do with boost. The current libboost-signals-dev package in debian is 1.40, while libxmmsclient++3 was build against 1.39. When promoe is stated, the dynamical linker uses the boost 1.39 shared library, which doesn't work correctly in this case.
The best way to fix this in my opinion is to make libxmmsclien++-dev depend on the exact boost version it was build against. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
