> The stack trace icon at the left hand side of the Logback View isn't always displayed. If a logging event
with a stack trace is displayed in the view first, the icon is displayed in the first row and the view seems to
work normally.
> But if an event without a stack trace is displayed first, without an icon, the icon doesn't seem to be
displayed for all subsequent rows.
> I think this might due to using a virtual table with a label provider that provides {{null}} column images.
I've changed {{getColumnImage}} to return a blank image instead of {{null}} if the event doesn't have a
stack trace, and that seems to fix the problem.
