Hello.
My first message contains the debug information (last part of the
strace output).
I am now going to add the last part of the diff between the strace
output of the working (1.6.8) versus broken (1.7.1) cryptsetup
(luksOpen):

The two versions show a different behaviour (the working version reads
SELinux configuration, the broken version opens /dev/urandom and gets
stuck), so the code must have changed.
If you need other information, please let me know. Obviously I cannot
post gdb output as the program does not crash, it simply gets stuck.
But it's a genuine bug...

Guido
