<br>The problem is that KCompactDisc is not getting a list of devices back from Solid/HAL because HAL isn't detecting my cdrom.<br><span style="font-family: courier new,monospace;">$> hal-device | grep ': udi'</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">0: udi = '/org/freedesktop/Hal/devices/computer_drm_r300_card0'</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">1: udi = '/org/freedesktop/Hal/devices/computer'</span><br style="font-family: courier new,monospace;">

<br>That's why it's not working, but that shouldn't make audiocd crash. A more descriptive error message like "Couldn't detect cdrom device, check HAL configuration" would be nice.<br><br>Should I submit a bug report?<br>

</div>You have to continue executing from there. That's the SIGSTOP signal that<br>
the ioslave sends itself so that you can attach.<br>

</div>Not build, but at least have debug symbols. And, of course, for<br>
kio_audiocd.<br>
