sudo md5deep -rel /* leads to system crash

[jessek]

As described at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=841447:

Dear Maintainer,

"md5deep -rel /" crashes my system (reboot) with a for me unkown reason. "sha256deep -rel /" crashes in the same way. This was tested on two different machines running debian stable and one machine running debian unstable all showing the same issue. A "md5deep -rel /* >> log.txt 2>&1" seems to run without crashing the system. While running "md5deep -rel /* >> log.txt" the log.txt showed that it crashed on reading a file in /home/user and the file ending constisted out of NULLS, but a "md5deep -rel /home/*" runs without any problem.
