f-spot eats my jpegs when i try to rotate them

this happens to any jpeg i try to rotate.

i import a jpeg file (made with dcraw and imagemagick)
select it
click either rotate button
photo is replaced with big question mark
the original photo is corrupted, it cannot be read with eog or gimp

the output on the terminal

sam@titania:~$ f-spot
