21179	"Sporadic crashes right after download - Failed to load module ""topmenu-gtk-module"" - BadWindow (invalid Window parameter)"	stanton	team	"==== What steps will reproduce the problem?
1. Start JOSM
2. Download from Overpass API with the following query (all milestones in Poland; this takes some time)

{{{
[out:xml][timeout:90];
area[""admin_level""=2][""name:en""=""Poland""]->.searchArea;
(
  node[""highway""=""milestone""](area.searchArea);
);
(._;>;);
out meta;
}}}


==== What is the expected result?

Data is downloaded and rendered; then I can start editing

==== What happens instead?

Sometimes this works as expected. Other times JOSM starts rendering (I still see the map view with the milestones very briefly), then it crashes.

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

Right now this behavior is fairly reproducible, i.e. the above steps crashed JOSM with every single of multiple tries. I did eventually manage to do a full download (directly from OSM) of a small area, then download from Overpass into the existing data layer: this time JOSM did not crash.

Running JOSM from the command line (`java -Djosm.restart=true -Djava.net.useSystemProxies=true --add-modules java.scripting,java.sql -jar /usr/share/josm/josm.jar`) and reproducing the crash tells me this is not an unhandled Java exception but a Gtk error:

{{{
Gtk-Message: 17:05:53.974: Failed to load module ""topmenu-gtk-module""
The program 'java' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 20887 error_code 3 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
