Build and test failures with Qt 5.6 and Qt 5.3

[Jan Kundrát]

Hi David,
thanks for looking into this. I'm happy that you find the additional 
coverage useful. At this time, the infrastructure cannot easily send out 
automated e-mails only upon a change in the state of a build job -- if 
someone has some time and is willing to improve this, I'll be happy to walk 
them through.

I'll see into doing this.

The build jobs appear to be running with LANG=en_US.UTF-8. My ssh setup 
apparently forwards these LANG and LC_* variables, so I cannot guarantee 
100% correctness, but here's how the number formatting works in root's 
bash:

[root at ci-el7-a-4 ~]# LC_ALL=C printf "%'.3f\n" 12345678.901
12345678.901
[root at ci-el7-a-4 ~]# LC_ALL=en_US.utf8 printf "%'.3f\n" 12345678.901
12,345,678.901

Is that a correct behavior?

Note that the failure is specific to Qt 5.6, which IMHO suggests that 
there's some behavior change in Qt.

It prints out "txt".

That line is missing:

[root at ci-el7-a-4 ~]# grep -c opendocument /usr/share/mime/subclasses 
0
[root at ci-el7-a-4 ~]# rpm -qf /usr/share/mime/subclasses
shared-mime-info-1.1-7.el7.x86_64

Cheers,
Jan
