Bug#787473: systemd: Segfault while adding a new job

Maybe i found another hint:

The only weird thing about the serial port of this QNAP TS-419P II is,
that the serial interface is used for both the front panel LCD and
buttons as well as the UART console. You can switch the mode with a
jumper on the mainboard, which you will have to do to access the u-boot
and initram consoles. The panel is controlled by the qcontrol package.
At boot time, qcontol takes over the serial port and talks to the panel
with its own protocol. Maybe qcontol does some weird things to the
serial port that lets systemd-tty-ask crash? All versions of qcontrol
are somewhat buggy. I'll try to deinstall qcontrol so it doesn't mess
with the serial ports. Maybe that helps.

Anyway, systemd-tty-ask should not crash.
