[holgermappt]

What steps will reproduce the problem?

1. Get the two images from ticket:10853: attachment:ticket:10853:fullexifgps.jpg​ and attachment:ticket:10853:noexifgps.jpg​
2. Download session file geoimage_ivd_edt_violation.jos
3. Start JOSM in the directory where the images are with the session file as argument
4. Select layer Geotagged Images 1
5. Merge with other layer (icon Merge this layer into another layer, click Merge in following dialog)

What is the expected result?

Comments

changeset:6964 moved Main.main.removeLayer() into GuiHelper.runInEDTAndWait(). There is no violation if targetLayer.mergeFrom() is moved into it too. But I don't know if that would cause other trouble.
