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.

You said that the current version of promoe was compiled using an older
version of libboost-singals, so I removed the libboost-signals package
and installed the older version 1.39, but it won't work:

florian@coyote:~$ aptitude search libboost-signals

Description: managed signals and slots library for C++
This package forms part of the Boost C++ Libraries collection.
.
Signals represent callbacks with multiple targets, and are also
called publishers or events in similar systems. Signals are connected
to some set of slots, which are callback receivers (also called event
targets or subscribers), which are called when the signal is
"emitted."

I might have been a bit unclear. The problem is, that promoe and
libxmmsclien++3 where compiled against different versions of boost.
So yes, at the moment, the Promoe package in Debian is broken (the
0.1.0-1+b1, 0.1.0 worked).

To fix Promoe, it has to be built against the same boost version xmms2
was compiled against.
For testing, I compiled the Promoe package using libboost1.39-dev
headers on my computer and that version works, while the package in
Debian and a version I compiled against boost 1.40 crash.

So , to fix this package, the maintainer will have to rebuild xmms2,
so that it is built against the current boost version, and then
rebuild Promoe.
To avoid the same problem when the next boost version gets packaged
for Debian, the dependencies of the libxmmsclient++-dev package have
to be modified (so that the package depends on libboost-dev (=
<version>) instead of libboost-dev).
(I'll file that as bug against xmms2 later/tomorrow).

So, for now you can only wait for xmms2 and promoe to be rebuilt and
curse whoever did the 0.1.0-1+b1 package (Or whatever bot), or rebuild
the xmms2 and promoe packaes yourself.
