This issue is explained at some length here: http://www.internettablettalk.com/fo...772#post218772

Long story short, the lcars-extras 4.1 package does restore all image files when uninstalled, but it doesn't update the icon cache, and as a result, the shutdown graphic stays behind until the user (or another package) updates the cache.

You can can update your icon cache (and restore the shutdown image to whatever is currently installed) by running the following command in a root shell. (see https://wiki.maemo.org/Root_access )

We'll fix the problem in our next release, by adding that line to the post-install and post-removal scripts for lcars-extras. Sorry for the inconvenience!
