Bugzilla Bug 179698

Emerging media-sound/banshee-0.12.1 fails to detect decodebin during the
configure script. Eventually the gst-inspect command ($
/usr/bin/gst-inspect-0.10 decodebin) will cause an instance of gconf2 to
consume 100% processor resources. I've never been successful in getting this to
emerge. The gst-inspect command can find the plugin if executed manually.



Reproducible: Always

Steps to Reproduce:
1. emerge =media-sound/banshee-0.12.1
2. Wait for gconf2 instance to consume 100% of a processor
3. Kill one of the 2 gst-inspect commands to cause the configure script to fail

Actual Results:  
See description.

Expected Results:  
Detected the decodebin plugin via the gst-inspect command.

bashee is not gnome.

This is still a problem with the newer ebuild. Does anyone have any idea what
might be causing this?

seems to me a bug caused by gstreamer and not banshee. Adding gstreamer herd
and see what they thing about this.

Any News on this bug ?

*** Bug 180931 has been marked as a duplicate of this bug. ***

As far as I can tell, this is still a problem. I am trying to track down which
package might be causing this. I have also noticed gnome-media behaving the
same way, but if I kill the instances of gst-inspect, it complains it couldn't
find the autosink but still seems to move on and successfully compile. All of
the installed gstreamer plugins have been installed and the gst-inspect
commands work from the command-line.

I'm running low on ideas.

Since the Gentoo devs are asleep at the wheel, I took it upon myself to figure
out why this keeps failing.

I had my PORTAGE_TMPDIR set to an NFS v3 share (as noted in the bug). Changing
this back to a local ReiserFS mount, everything emerged safely.

This bug is now 7 months old and no progress has been made. I certainly hope
this can be fixed finally.
