For that I need to boot my Raspberry Pi with a different SD card which
I haven't done yet.

But I found out some more stuff:

1) I first recognized with the state before the dinstall run of
   2016-04-04 20:54.

2) It also happens inside a screen session when the screen session
   initally was started on the Linux vt console and hence had

3) It even happens remotely inside such a screen session despite it's
   connected to an xterm via ssh. So I now can also check stuff

4) It still happens with apt 1.2.10 installed.

5) The backtrace on armhf is unusable:

Not sure if it's gdb which is broken on armhf or something else.
