When closing modem-manager-gui, the program get stalled. I managed to trace
into the address space via gdb, and detected that mmgui_addressbooks_close is
awaiting addressbooks->workthread (thread 5 identified from threadid) to
terminate (at addressbooks.c:1286), while addressbooks->workthread gets blocked
in syscall recv(2), called by mmgui_addressbooks_execute_akonadi_command (at
addressbooks.c:408), resulting a deadlock.
Backtraces of belated threads are attached.
