Thanks!,
It was an rtmpdump issue.

For ubuntu/debian users:
Official repository 2.4 has issues.
If rtmpdump is compiled librtmp needs to be also replaced to avoid a segfault issue. But gstream depends on the old librtmp.

I solved this by compiling rtmpdump statically:

make SHARED=no

I used svnpenn's branch
