Bug 49005 Preference page doesn't get enough space to draw itself
200312162000 There are cases where the preference dialog doesn't allocate enough space for a page to draw itself. The width of the page seems to be a few pixels short.
bundles/org.eclipse.jface/src/org/eclipse/jface/preference/PreferenceDialog.java
IPreferencePage newPage = node.getPage();
		if (newPage == currentPage)
			return true;
		if (currentPage != null) {
			if (!currentPage.okToLeave())
				return false;
		}
		IPreferencePage oldPage = currentPage;
		currentPage = newPage;
		
		currentPage.setContainer(this);
		
		
		if (currentPage.getControl() == null) {
			final boolean[] failed = { false };
			Platform.run(new ISafeRunnable() {
				public void handleException(Throwable e) {
					failed[0] = true;
				}
				public void run() {
					currentPage.createControl(pageContainer);
				}
			});
			if (failed[0])
				return false;
			
			
			Assert.isNotNull(currentPage.getControl());
		}
