ID 408772 - Changing Locale settings on Linux creates unexpected '.' errors.

Problem summary
Changing Locale settings on Linux creates unexpected '.' errors.

Specifically changing the numeric system to one that doesn't use '.' for decimal points causes the issue

Customer reported version
nuke.12.0v1

Customer reported platform
centos7

Steps to reproduce

Method one:

1) Open Terminal

2) Run the following command to change the locale numbering system:

export LC_NUMERIC=it_IT.UTF-8

3) Launch Nuke from the same terminal, it will load with an error dialog saying unexpected '.' in "5.2000" and all nodes created will load with unexpected '.' in "0.0". 

Method Two:

1) In CentOS 7, open Region & Language settings

2) Set the Formats to a region where a "," is used for a decimal point, such as España

3) Apply the setting and re-login the user to apply the setting.

4) Launch Nuke, it will load with an error dialog saying unexpected '.'

Expected behaviour
For Nuke to work correctly with difference numeric locales set

Actual behaviour
Nuke will load with an error dialog saying unexpected '.' in "5.2000" and all nodes created will load with unexpected '.' in "0.0".

Additionally Nuke will crash when creating Group nodes and is generally more unstable.

Workaround
Set the local settings to a number system that uses "." for decimal points.

This can be done by running the below command, before launching Nuke from the same terminal:

export LC_NUMERIC=en_GB.UTF-8
