@vkislichenko - I, for a short time, had domain-server and assignment-client running on the old Pi B model (Arm V6) not the newer B2 (Arm V7). The TBB library seems to need a lot of work on RaspPI. I have no idea what it's status is on the new B+ other than hearing it has issues, but, to get it running on the old B model I had to do some hacking forcing it to use "generic" hardware support. It could be the Arm V7 support is not exactly right. Also QT 5.3.2 can lead to subtle fails depending upon how it was compiled. In my case if I cross compiled QT from PC nothing worked - it all compiled on RaspPi and ran, but failed in odd ways. Compiling QT5.3.2 from source on the RasPi (several DAYS on the old B model) led to working binaries - mostly. While I can't really help you figure it out (no access to a B+) I can tell you you're going to have to get very familiar with gdb and start digging. It also seems sensitive to which version of GCC you use and how it was compiled as well. Wish I could offer more than good luck.
