Having this for all of KF5 would definitely be useful.

Clearly it spots additional issues compared to jenkins, the more CIs we have
the better for quality ;)

However I admit that I keep forgetting to take a look at http://ci-logs.kde.flaska.net/matrix.html
in addition to jenkins, so your email is very useful.

Ivan, can this be worked around?

Fixed.

Fixed.

You mean plasma-framework.
Nick, can you ifdef this depending on the Qt version?

I just committed more debug output in case of failure, to find out more.
The result is staggering, null bytes everywhere.

Possibly also related to null bytes, let's dig more after fixing karchive.

> - [5.6] kcoreaddons: different number formatting

This test sets a C locale. Could it be that on your system, the C locale
doesn't include having the comma as thousands-separator?
Or maybe the system's locale still interfers, i.e. KFormat format(QLocale::c());
isn't enough to -really- use the C locale?

Also a mimetype problem. kcoreaddons' kde5.xml adds "*.doc" as a pattern
for text/plain, but surely it doesn't mean for it to become the main extension.
Can you the value of QMimeDatabase().mimeTypeForName("text/plain").preferredSuffix()
on your system? Here's it's "txt", I suspect it's "doc" on your system. Not sure why yet
though, but let's first check that.

> - kservice, in all versions: test failure

It appears that your system doesn't know that opendocument inherits application/zip.
Do you have this line in /usr/share/mime/subclasses ?
application/vnd.oasis.opendocument.text application/zip

Martin, can you take a look at
http://ci-logs.kde.flaska.net/0c/0c4039dc8d4c3fa9eed18a4f5604a90648fe3e84/rebuilddep/rebuilddep-kf5-qt56-gcc-el7/d8b3c13/shell_output.log
?

> - plasma-framework, all versions: wrong dialog dimensions/offsets

Same as what we can currently see in Jenkins, so that one is more expected
than all of the others...
