mkv files have wrong position in 1.0.5

[Steffen.Roeber at hella.com]

Hi,
if I play .mkv files in my app, then seeking to a position i not performed 
correctly.
I have an filesrc, decodbin and an appsink.
If I call 
    gst_element_seek(GST_ELEMENT(m_pipeline), 1.0, GST_FORMAT_DEFAULT, 
GST_SEEK_FLAG_FLUSH,
      GST_SEEK_TYPE_SET, qMin(i_stamp, m_duration), GST_SEEK_TYPE_NONE, 
GST_CLOCK_TIME_NONE);


    gst_element_query_position(GST_ELEMENT(m_pipeline), 
GST_FORMAT_DEFAULT, &stamp);

then stamp contains same value as i_stamp, the stamp I want to set. It 
does not matter if I use stamp or frame mode (GST_FORMAT_DEFAULT or 
GST_FORMAT_TIME).
behaviour is same in both modes.
The problem is that the next buffer I get in my appsink has a stamp which 
is about 2-3 frame behind the frame I set. The problem occurs only in some 
.mkv files. Some work, other format like .avi or .mov also work.
