Bug 486830

Description Michael Wirth 2016-01-29 09:56:40 EST

In method IApplication#start open a new shell.

    ....
    final Shell loginShell = new Shell(display, SWT.NO_TRIM);
    new Label(loginShell, SWT.NONE).setText("Login");
    loginShell.open();
    ....

The first load of the page is ok, after reloading the page the following error occurs. This happens in Chrome on Mac OS X. In Safari and Thunderbird there is no error

Error: Error: Operation "create" on target "w2" of type "null" failed:
Cannot read property 'width' of undefined
Properties: 
style = NO_TRIM
