Help needed with meson build for modem-manager-gui

Hello everyone,

I'd be really grateful if someone versed in meson could help me fix build errors in modem-manager-gui.
The error is a bit of a random thing, as only some builds fail, and some work fine; I actually haven't been able to reproduce the error on my machines and only see it in Fedora builders.

The tl;dr version is that there seems to be some kind of race condition in the build script, and sometimes it will run into a situation where it tries to install a file that hasn't been created yet - this most often happens with translation files.

If you want to help out, here's the most recent build log: <a href="https://kojipkgs.fedoraproject.org//work/tasks/3908/32513908/build.log" title="https://kojipkgs.fedoraproject.org//work/tasks/3908/32513908/build.log">https://kojipkgs.fedoraproject.org//work/tasks/3908/32513908/build.log</a>

Thanks in advance,
A.I.

Hello,

[..]
perhaps the root-cause is itstool - i.e. it errors out some time before
the error message at the end of the log:

BUILDSTDERR: Installing /builddir/build/BUILD/modem-manager-gui-0.0.19.1/resources/modem-manager-gui-symbolic.svg to /builddir/build/BUILDROOT/modem-manager-gui-0.0.19.1-5.fc30.x86_64/usr/share/icons/hicolor/symbolic/appsTraceback (most recent call last):

There is an open bug report that describes some similar non-determistic
itstool behaviour - when called from gmake:
