I have this problem too, but it seems be different from everyone else's

Current Running widgets:
touchsearch
OM weather widget
feed widget
to do list (calendar)
OVI
media player

When i restart my phone
my media player doesn't work (I can open the media player, but i can't play songs from the widget)
What I have to do is delete the widget off my desktop and put it back there and it works again
I pan through my home desktop and my OM weather widget, and touchsearch dissapear.

Can someone try reinacting this to see if it crashes for you too. I was thinking maybe it's a bug with the media player, but I thought I read that someone had it complete disabled and the still have the same problems
