Bug#731782: konqueror postinst script quits with segmentation fault (update-alternatives)

[Markus Wagner <markus@mwagner.info>]

Package: konqueror
Version: 4:4.11.3-1
Severity: important

Dear Maintainer,

Installation of konqueror 4:4.11.3-1 fails due to a segfault triggered by the
postinst script

Steps to reproduce:
1. apt-get install konqueror/[jessie|sid]

Outcome:
Errors were encountered while processing:
 konqueror
 kde-baseapps
 kde-plasma-desktop
 kde-plasma-netbook
 kde-full
 kde-standard
 konq-plugins
E: Sub-process /usr/bin/dpkg returned an error code (1)

Expected:
Successful complete install

First analysis shows:
konqueror.postinst calls updated-alternatives like this:

root@brick:~# update-alternatives --install /usr/bin/x-www-browser
x-www-browser /usr/bin/konqueror 100             --slave /usr/share/man/man1/x
-www-browser.1.gz             x-www-browser.1.gz
/usr/share/man/man1/konqueror.1.gz
Segmentation fault

So it is either the use of update-alternatives or the current version of
update-alternatives.
root@brick:~# update-alternatives --version
Debian update-alternatives version 1.17.4.

Maybe related to #731710. If really duplicate feel free to close and sorry for
dupe.
