No rendering: GStreamer flow error

Description
Using Pitivi 0.92-1 from Debian experimental, I'm not able to render videos any more (as far as I can tell, I did not have too much problems with 0.92). For instance, on a multi-video project, I get the following error:
Sorry, something didn’t work right.
Erreur interne de flux de données. [~ Internal error of data flow]
gstbasesrc.c(2865): gst_base_src_loop (): /pitivi+utils+pipeline+Pipeline:pitivi+utils+pipeline+pipeline0/GESTimeline:gestimeline0/GESAudioTrack:gesaudiotrack0/GnlComposition:gnlcomposition1/GnlSource:gnlsource53/GstAudioTestSrc:audiotestsrc1:
streaming task paused, reason not-negotiated (-4)
The project looks fine to me, and the rendering options (e.g. resolution, frame rate) are the same as the input videos. I tried several codecs (webm with VP8, avi with x264enc), to no avail.
On the simplest project (just dropped a video, used the video properties as project properties, etc.), I get a fairly similar error:
Sorry, something didn’t work right.
GStreamer a rencontré une erreur générale de flux. [~ GStreamer encountered a general flow error]
qtdemux.c(4402): gst_qtdemux_loop (): /pitivi+utils+pipeline+Pipeline:pitivi+utils+pipeline+pipeline1/GESTimeline:gestimeline1/GESAudioTrack:gesaudiotrack1/GnlComposition:gnlcomposition3/GnlSource:gnlsource1/GstBin:audiosrcbin/GstURIDecodeBin:uridecodebin4/GstDecodeBin:decodebin10/GstQTDemux:qtdemux8:
streaming stopped, reason not-negotiated
In both cases, the error is blocking: no video is produced.
Not sure where to start with this one, the message is not really explicit to me... I'd be happy to provide more information, or to try other approaches/settings.
Mathieu.
