Description Adam Huffman 2008-08-17 17:42:30 UTC

Description of problem:
On Rawhide I'm having some trouble with the loading of blank optical media.  Sometimes when a disc is loaded, I see the following in /var/log/messages:

gvfs-hal-volume[3455] general protection ip:407f50 sp:7fffb5c6acf8 error:0 in gvfs-hal-volume-monitor[400000+1d000]

This means the "blank disc" icon doesn't appear on the desktop.

These are the kernel messages when this happens:

Aug 17 18:35:44 marcel kernel: sr 1:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK
Aug 17 18:35:44 marcel kernel: sr 1:0:0:0: [sr0] Sense Key : Blank Check [current]

Aug 17 18:35:45 marcel kernel: cdrom: This disc doesn't have any tracks I recognize!

Version-Release number of selected component (if applicable):
gvfs-0.99.4-1.fc10.x86_64

How reproducible:
With some discs

Steps to Reproduce:
1. Insert a blank disc
2.
3.
  
Actual results:
Sometimes no blank disc icon appears

Expected results:
The blank disc icon should appear on the desktop

Are you still seeing this ? There were some refcounting fixes in gvfs recently that might be responsible for this.

Comment 2 Adam Huffman 2008-09-09 07:43:12 UTC

Happened again just now, with latest rawhide:

Comment 3 Matthias Clasen 2008-10-04 03:55:38 UTC

David, this looks like a gvfs-hal-volume-manager segfault. 
Any idea ?

Comment 4 Bastien Nocera 2008-10-22 21:53:27 UTC

Could we please get a backtrace from the crash?

Something like this should get you a core dump:
ulimit -c unlimited
/usr/libexec/gvfsd -r # This replaces the currently running gvfsd

Comment 5 Adam Huffman 2008-10-22 23:29:34 UTC

Am not able to reproduce it at the moment - still see the kernel errors when a blank disc is inserted, but gvfs-hal-volume-manager doesn't crash.  Feel free to close and I'll reopen if it recurs.

what dvd writer is this issue about?

Comment 7 Adam Huffman 2009-04-01 07:29:01 UTC
