Public bug reported:

I have noticed (via the postinst script of Beyond Compare), that
`kde4-config -v` in the root directory ("/") goes mad:

  % cd /
  % kde4-config --version 2>&1 | head -20

`kde4-config --prefix` works fine, but also `kde4-config --help` goes mad.


When redirecting stderr, it "only" takes a few seconds:

  % time kde4-config --version 2>/dev/null
  Qt: 4.8.6
  KDE: 4.13.1
  kde4-config: 1.0
  kde4-config --version 2> /dev/null  5,17s user 0,46s system 99% cpu 5,644 
total


  % time kde4-config --help 2>&1|wc -l 
  774798
  kde4-config --help 2>&1  6,75s user 1,49s system 99% cpu 8,248 total
  wc -l  0,64s user 2,19s system 34% cpu 8,247 total


It appears to look at the following files:
  /boot/initrd.img-3.13.0-29-generic,
  /boot/initrd.img-3.13.0-30-generic,
  /usr/lib/x86_64-linux-gnu/libnss3.so,

Extracted via:

  % time kde4-config --version 2>&1|awk '{print $4}'|sort -u

  /boot/initrd.img-3.13.0-29-generic,
  /boot/initrd.img-3.13.0-30-generic,
  /usr/lib/x86_64-linux-gnu/libnss3.so,
  kde4-config --version 2>&1  8,28s user 1,68s system 95% cpu 10,396 total
