Sure... but still, the thread title is misleading, it has nothing to do with PR 1.2, nor hildon-home. You installed a nasty widget which kills kittens. If I were you, I would simply close all widgets on the desktop, reboot, and then I would start adding them one by one. If the issue appears, I'll know which one caused it. (If it happens with a built-in widget, file a bug report to http://bugs.maemo.org and prepare to receive some vague explanation about why won't it be fixed. In this case, you'll have to look for an alternative.)
