gvfsd-trash crashed with SIGSEGV in trash_item_invoke_closure()

[Paul White]

I started a live session using daily ISO 20190112 within KVM. I opened the Settings application, changed the Ubuntu dock icon size and when I closed Settings I saw a crash notification which led to the reporting of this bug report.

Tested today build 25.02.19 daily tests and was unable to repeat the error--changing icon size worked well for me. This was tested Live on a Dell laptop not in a virtual machine.

Changed to incomplete since not replicable. If the original poster could retest and if it's still a problem, provide clear steps and conditions to reproduce, that would be great. Thanks!

Closing my own bug report as "Invalid" as I:

1) Didn't see the crash again
2) Don't have Ubuntu 19.04 installed
3) No longer have KVM set-up to test
