-- Information about the crash:
I was dumping old CDs off of a usb dvd drive to images, for archival purposes.
After finishing the raw dump via command line tools (which just reads the block
device), and then copying the resultant image files to storage via Dolphin over
cifs kio, I briefly checked that the media had not been mounted (it hadn't) and
pressed the physical eject button on the drive to get my disc back.
Dolphin immediately crashed with the following stack trace.
I can reproduce this somewhat reliably, as it does not systematically occurs,
but reoccurs the majority of the time.
I in fact did it just now by reinserting the physical media, starting dolphin,
waiting for everything to settle (not mounting anything) and just hitting the
eject button.
If it helps, since Dolphin helpfully reads the disk labels and presents them in
the side bar for easy mounting, the media was an Apple HFS disk.
I am unsure of how much this helps, but here is the disk layout and properties:
--- /dev/sr0
Block device, size 647.7 MiB (679211008 bytes)
CD-ROM, 1 track, CDDB disk ID 02114501
Track 1: Data track, 647.7 MiB (679211008 bytes)
Apple partition map, 3 entries
Partition 1: 31.50 KiB (32256 bytes, 63 sectors from 1)
Type "Apple_partition_map"
Partition 2: 647.4 MiB (678871040 bytes, 1325920 sectors from 64)
Type "Apple_HFS"
HFS Plus file system
Volume size 647.4 MiB (678871040 bytes, 165740 blocks of 4 KiB)
Volume name "Microsoft Office 2004"
Partition 3: 8 KiB (8192 bytes, 16 sectors from 1325984)
Type "Apple_Free"
Blank disk/medium
The crash can be reproduced sometimes.
