Latest cvsup to 7.0 causes mplayer to crash my system

Hi,

Today I've buildworld on latest cvsup (from -CURRENT_at_july 8th) and now 
whenever i try to play a movie with mplayer, my system crashes with :

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x1c
fault code              = supervisor write, page not present
instruction pointer     = 0x20:0xc06a0bc3
stack pointer           = 0x28:0xe502fc88
frame pointer           = 0x28:0xe502fcc8
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 28 (swi4: clock sio)
trap number             = 12
panic: page fault
Uptime: 7m49s
Dumping 1023 MB (2 chunks)
  chunk 0: 1MB (159 pages) ... ok
  chunk 1: 1023MB (261808 pages) 1007 991 (CTRL-C to abort) 

and a 1gb dump. That same system was fine on 6-CURRENT from July 8th so 
something in between breaks it. The crash message is always the same. I tried 
recompiling mplayer which did no good.

Please help,
Nicolas.
