I finally found the time and tools to reproduce the segfault in 
dbus-daemon 1.6.4 and obtain a dump. 
A colleague of mine will proceed with the analysis. Nevertheless, I 
already want to share the dump 
in case someone is interested (or already knows if/how the issue was 
fixed):

(gdb) quit

Does someone already know what happened and how to avoid the issue?
