during backtrace loading the widgets get mutated a lot, changing their size
to very long, or very short, but certainly different than from what they
were originally when the window was sized.
as a result the window may now be too small to actually fit the content and
overlap some of the widgets. to resolve this problem we now force a size
adjustment when the backtracewidget changes. other pages, from what I
can tell are not affected.
the layout of this page is a fairly involved unfortuntely, so adjusting
on the fly is the best we can do I fear
CHANGELOG: The crash dialog no longer cuts off text after backtracing
