the sizeconf MSFilter converts from any image size in the set {QVGA, QCIF, 
CIF} to what it is told to do in vsize (by default CIF).
The stream->output MSFilter displays the pictures it receives using the format 
it is told in vsize.

This is the symptom of a SIGSEGV. You should execute linphone from gdb to see 
where the memory fault happened.
