Not much if a bug reporter normally, since the few times I've done it, It has always seemed to be wrong somehow. However since this is an outright consistent crash, I though it report it. Tried looking through the frequent list, but it all gets a bit to technical for me.

1) Opened F-Spot once
2) Imported my photo library - all taken with either a Canon Digital Rebel XTI/400D, SonyEricsson K660i or a Sony DSLR-A100. Some photo's have been retouched with Picasa or The Gimp. 
3) F-Spot consistently crashes on startup.

Running on Ubuntu 10.10 (Upgraded since Lucid), Gnome 2.32.0 with Compiz enabled, on a Thinkpad T61 widescreen model with an extra GB of ram installed.
