Failed to export to JOSM from Overpass Turbo (Reporting as requested by JOSM)

[davebulow@…]

What steps will reproduce the problem?

1. From Overpass Turbo I ran the following:

{{data:sql,server=https://postpass.geofabrik.de/api/}}

SELECT tags, geom
FROM postpass_pointlinepolygon
WHERE tags ? 'fixme'
AND geom && {{bbox}}

2. Clicked 'Export'
3. Clicked 'JOSM' under 'load data into an OSM editor'

What is the expected result?

Receiving the highlighted OSM features from Overpass Turbo in JOSM

What happens instead?

'You have encountered a bug in JOSM'.

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

Thank you for all your hard work on JOSM! I ran the exact query in Overpass Turbo that is suggested by OpenStreetMap on day 3 of the 31 Day Challenge, as shown here. "​https://wiki.openstreetmap.org/wiki/31_Day_OSM_Challenge" So you may receive similar bug reports from others in the coming days!

Once again thank you for all your work and help.
