Crash after downloading OSM data.

[bigshot4ever@…]

What steps will reproduce the problem?

Just download some OSM data.. no difference with big or small areas.
Everything seems ok until the status bar reach the end ("Preparazione dell'insieme dei dati" -> "Preparing the data set").

Same problem. Before this started to happen, I managed to download some data successfully.

Problem persists with 4127

Steps to reproduce:

1. Clean .josm settings
2. Resize the main window
3. Download a data set
4. Detach "properties" and "layers" side panes and place them outside the main window
5. Close JOSM
6. Open JOSM
7. Download a data set

A Xinerama double-screen setup might be necessary.

Workaround:
replace all occurrences of "docked=false" with "docked=true" in .josm/preferences
