gtk20 segmentation fault

[mc]

hi,
i got a segmentation fault last week running port audio/jamin after this 
error

    Gtk-WARNING **: GtkSpinButton: setting an adjustment with non-zero
    page size is deprecated
    Segmentation fault (core dumped)

but today i am getting the same error running x11-wm/obconf
i tried deinstalling gtk20 a few times woth no effect , however only the 
first deinstall said something about a csum mismatch,

is this port not building properly or something else?

i have fedora 10 in virtualbox and got the same error running obconf, 
but it doesn't fault and runs- still i don't know what that means. is 
there anything else i might rebuild?

freebsd 8.0rc1 amd64
