Recently I've discovered when one marks a window "sticky" in Fluxbox, iconify it, move to another workspace and then deiconify the window Fluxbox will crash. This is repeatable for all windows with fluxbox-0.9.14-r1.
Oops forgot emerge --info.

Hrm, I can't reproduce this here, can you try 0.9.15.1 and see if it does the same thing there?
It appears fixed in fluxbox-0.9.15.1, but not fluxbox-0.9.15 or fluxbox-0.14-r1.
Closing bug as it is fixed in 0.9.15.1 which is keyworded stable on amd64. (-r1 and -r2 at least)
