[news.eclipse.tools.gef] Re: Crash with empty Labels on Linux

[Billy Biggs <bbiggs@xxxxxxxxxx>]

A snippet would be very helpful.  X is asynchronous, but in SWT there is
a way to put it in synchronous mode so you can get a stack trace of
where the failure occurs.  When creating the display:

  Device.DEBUG = true;
  DeviceData data = new DeviceData();
  data.debug = true;
  Display display = new Display (data);

The X request which is failing here is an XCreatePixmap, so this might
have to do with an icon somewhere failing...
