How to manipulate with Gst.Caps' in C#?

[wl2776]

I need to get a copy of Gst.Caps and then remove several fields from it.

I do this in the following way.

taget_caps = caps1.Copy();
for (uint i = 0; i < caps1.Size; i++) {
  Gst.Structure st = target_caps[i];

  if (st.Name.ToString().Contains("video")) {
    st.RemoveField("parsed");
    st.RemoveField("codec_data");
    st.RemoveField("profile");
    st.RemoveField("level");
    st["bitrate"] = video_bitrate;
  } else if (st.Name.ToString().Contains("audio")){
    st1.RemoveField("parsed");
    st1["bitrate"] = audio_bitrate;
  }
}

However, when my application finishes, I get the exception, saying:
"Additional information: Collection was modified; enumeration operation may not execute."
Call stack shows Gst.Caps.Finalize(), line 242 and Gst.Caps.RemoveStructureReferences(), line 59

Is there anything like DeepCopy for GstStructures? Google shows only variants, subclassing from ICloneable

Looks like there's a bug somewhere in the C# binding.
Currently have passed it using strings and .FromString and .ToString methods.

Will try to update fresh git revision and file a bug if one will exist, when time permits.

This is probably already solved in git.
