Rhythmbox shouldn't be scanning the video files

Thanks for your bug. Could you describe what is your issue exactly? Rhythmbox looks on the type of the files and import only audio ones. What version of rhythmbox and Ubuntu do you use?

so it is opening the viedofiles and reading them just to know that they are video? shouldn't it be using the mime-types for that?
My real problem is this:
Rhythmbox Crashing on playing a song and listing a dir

But it was first happening with a videofile that it was trying to scan before the song on the other bug. As all software have bugs, why don't it limit the chance for error just opening and using gstreamer to read the audio files? and in cases where there are videos and music mixed it would also be faster.

It does not open the videofiles and read them, it asks for the mimetype, but the mimetype detection might go wrongly. Could you run "gst-launch-0.10 -t filesrc location=/path/to/my/video ! decodebin ! fakesink" and copy that to a comment?

I just want to say that before I had pitfdll and now I don't, so if
the problem is in there it will not show up anymore.
Here it is:

:/mnt/dados/clip/Clipes $ gst-launch-0.10 -t filesrc

Rhythmbox has to scan all files, because until it scans them it doesn't know whether they contain audio and/or video. Mimetypes aren't enough, because many types like application/ogg and video/quicktime are just containers, and so may contain audio (Vorbis, AAC) or video (Theora, QT video).

The problem of RB crashing on imports has been fixed for 0.9.4, if the metadata-helper is enabled (which it is by default). Using that importing is run in a separate process, so crahes in GStreamer won't kill RB.

Marking as rejected as since explained by James the format detection requires to do that, that's not a bug
