columns width resets on start

[michel]

it's easier to show the screenshot than to describe the problem.
it happens sometimes when deluge starts. closing and restarting gives the same result, so i have to rearrange the columns width manually.
i don't know if it is important: as you can see the ratio is resetted also. but sometimes it's just the ratio that's been resetted, not the columns width.

deluge 0.5.6.2 on ubuntu gutsy i386
