I have just asked the website admins to remove the Fedora 12 LXDE Spin from the BitTorrent Tracker because we found a severe bug that makes the images unusable. The problem is a crash in lxde-settings-daemon that triggers abrt, the automatic bug reporting tool. Because lxde-settings-daemon gets restarted by lxsession the bug reporting tool goes into an infinite loop, consumes all CPU power and makes the computer crash when the overlay image of the live OS is filled up.
I have no idea why we didn’t spot this bug before. I have tested every nightly and they all were fine, but they were created on a different machine then the final images. Also installing LXDE from the package repositories works fine, so you can already install LXDE on Fedora 12.
There will be fixed images soon. I’d like to ask you for three more days of patience. Apologies for the inconvenience.
