Title:
  gvfsd-mtp crashed with SIGSEGV in ___pthread_mutex_lock()

Status in gvfs package in Ubuntu:
  New

Bug description:
  New bug because matching existing bugreport is of 2017.

  automatic data collection, not checked.

  Right before the crash, I had a "Dateien" / "Files"
  https://wiki.gnome.org/action/show/Apps/Files window open, showing
  contents of my attached mobile phone.

  upon clicking on "eject" button in "Files", a message box "already
  disconnected (with [ok / cancel] iirc)", as always, appeared - and the
  crash report next.

  Though this seems not to be reproducible. There were other actions before:
  - moving one huge file to another folder (via "Files", but within mobile 
phone)
  - moving or copying some files from mobile phone to ubuntu
  - deleting some 25 GB of data files (photos and videos) that were copyied.

  Additionally, there were some updates, including request to reboot,
  which is not done yet.
