<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">https://bugs.kde.org/show_bug.cgi?id=314544#c40 says:
"Looking at the backtrace, KFilePlacesItem tries to detect Audio CDs as follows:
Solid::Device d = device();
if (d.isValid()) {
if (m_access) {
return QUrl(KUrl(m_access->filePath()));
} else if (m_disc && (m_disc->availableContent() & Solid::OpticalDisc::Audio)!=0) {
QString device = d.as<Solid::Block>()->device();
return QUrl(QString("audiocd:/?device=%1").arg(device));
}
}
The crash happens, because d.as<Solid::Block> returns 0, in other words, Audio CDs are no longer treated as block devices.
Failure of said cast can be easily detected, but the question is rather, if it's not a Solid bug, how the code needs to be modified to correctly get the audiocd:/ URL for the block device."
While I did not yet figure out, how I can get the block device URL for a disc in case block is 0, I propose this temporary fix. It should fix the crash, but could fail to correctly invoke the audiocd:/ kio with multiple disc drives.</pre>
