Mapillary import images causes 'Exception error'

[vandalfsen@…]

What steps will reproduce the problem?

1. Start JOSM with Mapillary plug-in activated
2. Download some data from OSM
3. Select "Afbeeldingen importeren" from menu "Bestand" (Translation: Import images, File)
4. Double click a folder to change to it.

What is the expected result?

The "select images"-window shows the contents of the folder.

What happens instead?

A exception error occurs, but the window which should inform you of this hides behind the "select images"-window.

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

Thank you for reporting this issue.

Probably you have a file in that folder, that is empty (i.e. it has a size of 0 bytes), right?

I fixed that issue now, but it might take a while until you can update the plugin through JOSM to that new version.

If you want to try it out before the fixed version gets distributed via JOSM's plugin update mechanism, you can download the Mapillary.jar from ​https://github.com/floscher/josm-mapillary-plugin/releases/tag/v1.2.1-beta.1 and place it in your ~/.josm/plugins/ directory.

Replying to floscher:

I did have a empty file there. I opted to remove it and now the mapillary plug-in works fine. (JOSM happened to be updated too, but I guess that didn't change the situation.)

Thank you for your time and efforts.
