"kde4-config --version" in / goes mad: looks into /boot/initrd.img-3.13.0-29-generic etc

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
  "KConfigIni: In file /boot/initrd.img-3.13.0-30-generic, line 3: " Invalid entry (missing '=')

`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
