Package: libqt5core5a
Version: 5.4.2+dfsg-4
Severity: normal

Dear Maintainer,

I've upgraded the Plasma desktop to Plasma 5, and the new desktop fails to start.
Looking into the problem I've realized that several components (kwin_x11, plasmashell,
several of the systemsettings5 modules...) finish showing the message
"This program requires an X86 processor that supports SSE2 extension, at least a 
Pentium 4 or newer" in the console.

I've also checked that a non-kf5 program such as 2048-qt also fails to start with
the same message.


As per http://lists.qt-project.org/pipermail/development/2013-December/014530.html
I understand that all or some Qt5 packages are built with SSE2 requirement enabled.

>From that link and from experimentation, I think the crashes only occur in programs
that use QML. For instance, the KF5 version of KWrite and Konsole work fine.


I understand a machine such as this Celeron is ancient, but maybe it would be possible
(and worthwhile) to provide some kind of dual/conficting packages for some of those
libraries, with and without the SSE2 requirements.


This is just a test machine for me, it's not like I need this, but after a little
discussion on #debian-kde, I thought it was worth a bug report ;)

I'm reporting this to libqt5core5a since seems to be about a general Qt5 thing.

Cheers, and thanks for all the great work you all do!




   * What led up to the situation?

	Upgrading Plasma 4 to Plasma 5 in Sid, on an old Celeron machine.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

	Starting a Plasma 5 session.

   * What was the outcome of this action?

	Several things crash.

   * What outcome did you expect instead?

	Desktop showing at least partially.

   [ Dmitry Shachnev ]
   * Drop obsolete Breaks/Replaces. Qt versions before 5.3.2 were never part
     of a stable release (Jessie and Wheezy-backports have 5.3.2).
 .
   [ Lisandro Damián Nicanor Pérez Meyer ]
   * Do not make lack of SSE2 support on x86-32 fatal by using Guillem Jover's
     patch (Closes: #792594). Thanks Guillem!
