GUI: SIGSEGV when running ./scummvm with disabled translations on macOS

Description

This is on macOS Mojave 10.14.6 (with a Retina screen).

Building from Git with the following configure options:

./configure --disable-all-engines --enable-debug --disable-translation

and then just running ScummVM this way:

./scummvm

gives me an immediate "Segmentation fault: 11" error, unless I stop building with --disable-translation.

Of course, if I just run it this way, most .dat files won't be found, so I fall back to the builtin theme, translations won't be found, engines requiring dat files would fail, and so on. So it's not the good way to run it, but it works for most of my quick tests, and I think that it should at least handle this use-case in a more graceful way than a SIGSEGV, here (?).

git-bisect seems to relate this to commit 65e38680dda3d631b25f01498dbc0f6fc84186cf (where there is indeed a USE_TRANSLATION ifdef).

lldb backtrace is attached.

@dwatteau: This shouldn't really crash, but given your backtrace and the bisection you have indicated, it appears this is failing to parse the theme file and load any fonts, thus it crashes when it tries to size the first font when rendering the GUI.

I think this might be an issue with the scummvm configuration file, specifically the theme path which is probably defaulting to the standard installation location rather than the location of your local build tree.

You might want to check the theme path is set for the gui/themes directory of your development build folder: https://docs.scummvm.org/en/v2.2-docs/settings/paths.html?highlight=theme%20path

The keys are gui_theme and themepath in the scummvm configuration file used:

The point here is that running a local development build from git _usually_ works fine with the older installation configuration file, themes etc. but if the themes are updated, fonts added... then this can break if the theme and extra paths are not changed from the default to a specific path for the development git tree version.

I can reproduce the issue. This is a regression from 65e38680d (GUI: Added XML theme setting for overriding the fonts depending on the selected language.).
It indeed fails to load any font, and I think I know what is wrong. I should have a fix for it soon.
