Bug#561565: compiz-fusion-plugins-main: Thumbnail (Taskbar window preview) crashes compiz on empty title

[Klaus Knopper <bugs@knopper.net>]

Package: compiz-fusion-plugins-main
Version: 0.8.2-3
Severity: important


/usr/lib/compiz/libthumbnail.so supports showing the selected windows
preview in the taskbar of the desktop manager. If a window
has an empty title string, compiz crashes as soon as the thumbnail is
supposed to be shown when the mouse is put over the windows taskbar icon.

The crash does not appear if "Enable titles" is deactivated in the
plugins configuration, therefore its likely to be a string null pointer
problem.
