Please describe the problem:
I'm using amaroK player with gstreamer (latest CVS sources) and i have SIGFPE
during playing mp3 file.

amaroK error log follows:

amarok: [GstPadLinkReturn gst_equalizer_link(GstPad*, const GstCaps*)] 
amarok: [GstPadLinkReturn gst_equalizer_link(GstPad*, const GstCaps*)]

Steps to reproduce:
1. On amaroK i play some mp3, during switching between them, amaroK hangs
2. When i run amaroK from gdb error happens on first mp3
3. It happens for any mp3 file i checked (it's not specific for any particular file)


Actual results:
program hangs

Expected results:
play song ;-)

Does this happen every time?
yes

Other information:
I'm using Mandrake 10.1, Intel 810 soundcard (i know it is problematic !)
Latest CVS version of alsa, amaroK, gstreamer, gst-plugins !

I suppose it is connected with CAPS negotiation with alsasink !

When i choose osssink everything plays perfect ! (so workaround is simple)
