(segfault in gst-launch pipeline with audioiirfilter)
Playing with gst-launch, I found the following:
$ gst-launch-1.0 filesrc location=test.mp3 ! decodebin ! audioconvert !
audioiirfilter ! autoaudiosink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

Then, using gdb, this seems to be the guilty thread:
