Description
When changing regional setting in windows, we have some issues if the decimal symbol and digit grouping symbol are the same.
- In English language systems if both symbols are coma it will start and hang.
- In Dutch language systems if both symbols are dot it will start and hang.
In Qt there is a warning:
qtbase\src\corelib\text\qlocale.cpp:767 qWarning("System-supplied decimal and grouping character are both 0x%hx", group);
And in this case its the warning that causes the hang (a mutex can't be locked twice), it has to do with creating logging categories.
