Dinamically change filesrc in videomixer

[kususe]

I'd like to change filesrc in videomixer in order to overlay images generates
in according to a timestamp. 
So, I started implementing the pipeline with a fixed image and it works. 
Then, I tried to, after creating png file, to overlay it, changing the state
of pipeline to READY, setting the new filesrc, thern again to PLAYING. 
But it doesn''t work and I have to stop using shell the script and kill it. 

Suggestions?

(original purpose is to overlay images in according to a timestamp. 
Coglogoinsert gets me a segfalut, yet reported to bugzilla, not yet worked
out.
Rsvgoverlay gets me a memory leak, reporting soon)

Thanks in advance
K.
