Linux: SasView >5.0.1 binary cannot copy default custom_config.py

[franzlang]

I have found that the Linux release binaries for SasView versions 5.0.1 and above give the following error when executing the run_sasview.sh script:

ERROR: Could not copy default custom config.
Traceback (most recent call last):
  File "sasview.py", line 117, in <module>

Version 5.0.0 works fine and creates the custom_config.py file upon first launch. Once this file exists, versions 5.0.1 and above also launch.

As we are close to releasing 5.0.3, maybe this needs looking at?

given 5.0.3 has left the station am moving this to 5.0.4

Closing this issue in favour of #1672
