That is because g_get_home_dir(), which is used by Hildon in the process of generating thumbnail URIs, ignores $HOME. I have not yet decided what to do with it. If you want an immediate workaround, you can symlink /root/.thumbnails to /home/user/.thumbnails/. I hope you know that only killing the Hamster will make you a real superuser. If thumbnails work despite the violence, there is something atypical with your setup. Well, in my head I have always pictured Aapo, whose packages account for half of the repository, as a competent guy. I even googled that bug to see if it is perhaps just copy-pasted from somewhere by mistake. I think it is not hard to notice that Hamster is already optified, so I started to wonder if there are other benefits behind that dependency, but seeing that no one has an approving explanation, I am removing it from the list. Yes, there are two preinstalled commands: Notes, Terminal (current dir). However, they are added only if the list is blank and untouched, thus usually do not appear after an upgrade. As promised, Hamster Filer 0.6.4 is out. Added location history, currently operable only with keyboards shortcuts (Backspace, Shift+Backspace). Added persistent mode for the location editor. Added an option to save location on exit. Added some error messages related to file renaming. Added a note that restart is required for the superuser setting to take effect. Initially select only the base name in filename input fields. Unlocked the ability to edit the applications list right before opening a file. Use a URI when opening a file with its default application, which should improve compatibility with some applications. Better recovery from an invalid starting location. Do not show the second location info field in attention dialog for remove operations. Decreased the margin in the settings window to avoid horizontal scrolling with wider fonts. Force dates to be in English for consistency. Some tweaks in the packaging. The mysterious "persistent mode", can be turned on to prevent the location editor from disappearing every time the location is changed. In this mode it will be replaced by the breadcrumbs only when you press 'X'. I have promoted the package to extras-testing, so give it a whirl and express your approval (or lack of) by voting here: http://maemo.org/packages/package_in...filer/0.6.4-1/.
