Phonon upstream believes that this is a libasound crasher that may have been remedied by http://git.alsa-project.org/?p=alsa-lib.git;a=commitdiff;h=91c9c8f1b85e69b4bdc94a777d2767c4906c3f47 (Post-1.0.23 fix)

Testcase from upstream:

1. export PHONON_PULSEAUDIO_DISABLE=1
2. export PHONON_GST_AUDIOSINK=alsasink
3. dragon somefile.ogg (likely any phonon client will do).
