[Python-modules-team] Bug#925403: libqscintilla2-qt4-13: please add Breaks: libqscintilla2-3

[Andreas Beckmann]

Package: libqscintilla2-qt4-13
Version: 2.10.4+dfsg-2
Severity: important
Tags: patch

Hi,

while analyzing piuparts upgrade logs for multi-distro upgrades
  lenny -> squeeze -> wheezy -> jessie -> stretch -> buster
I noticed some strange debsums errors like in the attached log:

9m25.8s ERROR: FAIL: debsums reports modifications inside the chroot:
  debsums: missing file /usr/share/qt4/translations/qscintilla_ru.qm (from libqscintilla2-3 package)

I couldn't figure out where exactly that file gets "lost", but I tested
that adding a Breaks against libqscintilla2-3 (from lenny) to the
successor library libqscintilla2-qt4-13 in buster successfully caused
the obsolete library package to be removed (and the problem therefore
"disappear".

I'm considering to NMU qscintilla2 with the attached patch to get
this fixed in buster.
