           Summary: The adder cannot handle when multiple elements tries to
                    link at the same time
           Product: GStreamer
           Version: 0.10.7
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base

Please describe the problem:
When multiple elemenst try to get linked to the adder very quickly after each
other, the adder fails to link to them, stops the adding (dies?), and spits out
the following warning and error:
GStreamer-WARNING **: Pad list changed during capsnego for element adder0
GStreamer-CRITICAL **: pad adder0:sink6 returned NULL caps from getcaps
function

I don't have any simple example code since the code producing the bug is part
of a larger application.


Steps to reproduce:
1. Create a pipeline with an adder and multiple audio inputs.
2. Link one of them and start the playback.
3. Link the rest of them to the adder quickly after each other.


Actual results:
This produces the warnings and errors:
GStreamer-WARNING **: Pad list changed during capsnego for element adder0
GStreamer-CRITICAL **: pad adder0:sink6 returned NULL caps from getcaps
function

Expected results:
If this worked correctly the adder should link the elements to itself, without
any errors

Does this happen every time?
yes
