Previews loading more than 454 lines of description text crash Unity

[David Callé]

Working preview:
title = 'test title'
description = 'test line\n' * 454
Unity.GenericPreview.new(title, description, None)

Crashing preview:
title = 'test title'
description = 'test line\n' * 455
Unity.GenericPreview.new(title, description, None)

WARN 2012-10-15 11:10:32 unity.dash.previews.preview Preview.cpp:53 Unable to create Preview object
Segmentation fault (core dumped)

Doing this previously resulted in a black square on the right pane (see https://bugs.launchpad.net/unity/+bug/1039437 ), since the addition of the spinner for previews taking a long time to open, Unity segfaults.

Please attach a stacktrace of the crash ;-)

Problem occurs because openGL's texture dimension limit is 4096px, and the texture creation failure this is not handled cleanly.

[Nick Dedekind (nick-dedekind)]

Requires fixes to both nux and unity.

      (LP: #1076763)

      directly. We don't care if the migration code isn't executed.
