Crash due to locale change from Gtk3

[bash0]

On Linux Mint 22, gmusicbrowser 1.1.99.1 is very unstable and crashes often. It turns out that right after the initial call to
use Gtk3 '-init';
the locale for interpreting further code change, in this case to German, where the comma is expected as a decimal separator instead of a dot. Thereafter, all literal floating point numbers in the Perl code get trimmed to their integer part, which obviously leads to loads of errors. The GTK version is 3.24.41.

[bash0]

As a workaround, I inserted a reset of the locale
use locale;
use POSIX qw(locale_h strtod);
setlocale(LC_NUMERIC, "en_US.UTF-8");
right after the use Gtk3 '-init';. I can't say if that is the right way to go, and if it fixed all the problems, but gmusicbrowser seems to be running smoothly again with this.

This issue seems to have the same root cause as the issue #253.
