I don't think this is a 64-bit or AMD issue. Running 32-bit: : samhain_pmurphy; uname -a Linux samhain 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:20 UTC 2008 i686 GNU/Linux : samhain_pmurphy; cat /proc/cpuinfo | grep ^model\ name model name : Intel(R) Pentium(R) M processor 1.86GHz : samhain_pmurphy; and I get the same symptoms: f-spot (which was working fine under 8.04) no longer works after I upgraded (not re-installed) to 8.10. Debug trace below. One other point: I have the screen saver set to show f-spot favourites, and *that* continued to work up to the point where I tried running f-spot from the command line. This was after the 8.10 upgrade. Finally, I ran it from my regular account (which had thousands of imported photos) and also from a "virgin" clean account which had never run f-spot before. Same end result (f-spot died) but different traceback. Also shown below (2nd traceback). : samhain_pmurphy; f-spot --debug ** Running f-spot in Debug Mode ** ** Running Mono with --debug ** [Info 14:27:43.508] Initializing DBus [Debug 14:27:43.739] DBusInitialization took 0.20894s [Info 14:27:43.739] Initializing Mono.Addins [Debug 14:27:44.098] Mono.Addins Initialization took 0.35828s [Info 14:27:44.110] Starting new FSpot server [Debug 14:27:44.461] Db Initialization took 0.155755s [Debug 14:27:45.084] QueryToTemp took 0.000943s : SELECT id, time, uri, description, roll_id, default_version_id, rating, md5_sum FROM photos WHERE id NOT IN (SELECT photo_id FROM photo_tags WHERE tag_id = 2) ORDER BY time DESC The program 'f-spot' received an X Window System error.
