Exception while opening 'Open' window

[stephane.vanerp@…]

What steps will reproduce the problem?

1. Fresh new installation of JSOM. Download of some maps already done.
2. Simply click on the 'Open' menuitem in the 'File' menu
3. The modal window of 'Open' is opened BUT, at the same time, a bug is reported.

What is the expected result?

Navigate through personnal folder. Select a file to be opened.

What happens instead?

No file at all is diplayed from my root path (/home/steph/). No subdirectories too.

Please provide any additional information below. Attach a screenshot if possible.

As you can see in the trace below, I have a folder 'Vidéos' in my personnal profile. Vidéos is french typed, i'm belgian. It seems to be an encoding problem.

Thanks in advance for the reading.

This is an encoding problem. You need to set a proper LANG= or use only ASCII.
