executing the command

nautilus --version

in a terminal window also crashes.

For verification I downloaded ubuntu-21.04-beta-desktop-amd64.iso (Ubuntu 21.04 "Hirsute Hippo" - Beta amd64 (20210331.1)) started it in VirtualBox ("Try Ubuntu") and also experience a crash for the "nautilus --version" command, see attachment.

Is this still Bug #1820859 ?

[Sebastien Bacher (seb128)]

The original description is confusing, it states after login but the recorded command is

 ProcCmdline: nautilus --version

so yes it does sound like bug #1820859

[Manfred Hampl (m-hampl)]

to the "confusing description":

Maybe a misinterpretation on my side. I booted the system, logged in, and immediately received a pop-up informing me of a crash. This might have been caused by the presence of a not-yet-reported crash file from an earlier session, although I cannot remember that I have executed "nautilus --version" earlier.

Only upon seeing the crash report and the bug report that has been created, I executed "nautilus --version" (or maybe executed it again) and with that command I reliably can produce that crash again.

Meanwhile I have downloaded the hirsute-beta-iso from March 31.
Booting it in "Try Ubuntu" mode in VirtualBox also reliably crashed when running "nautilus --version".

[Sebastien Bacher (seb128)]

right, thanks for the command and indeed the version argument is broken
