Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
  gnome-shell crashes after tracker-extract-3 reports "Not a JPEG file:
  starts with 0x89 0x50"

Status in gnome-shell package in Ubuntu:
  Incomplete
Status in xwayland package in Ubuntu:
  Incomplete

Bug description:
  System :
  Ubuntu 21.10
  Kernel 5.13.0-35
  Session : Wayland

  Each time I try to rip a CD with "abcde" gnome-shell crashes
  What I understand from the logs :
  Before the CD is ripped, abcde downloads a picture (from internet) as a cover 
of the CD.
  When tracker-extract discovers this picture something bad happens.
  Then gnome-shell crashes.
  After the crash (and re-login into Ubuntu) I can resume the ripping process 
as the picture has been cached by abcde, and tracker-extract does not interact 
again with it.
  Obviously the problem is back for each new CD.

  The problem appeared quite recently, probably less than 1 month ago.
