Per http://www.kernel.org/doc/Documentation/robust-futex-ABI.txt
For robust_futexes to work, the user code (typically in a library such
as glibc linked with the application) has to manage and place the
necessary list elements exactly as the kernel expects them. If it fails
to do so, then improperly listed locks will not be cleaned up on exit,
probably **causing deadlock** or other such failure of the other threads
waiting on the same locks.
The strace log in comment#12 shows the dialog was locked by futex. I'm afraid
g-s-dialog stumble into a bug of glibc :\
