Nautilus hangs when right-click->properties is selected on file

[Kalle Tuulos]

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

Ubuntu 18.04.3 LTS

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center

nautilus:
  Installed: 1:3.26.4-0~ubuntu18.04.4
  Candidate: 1:3.26.4-0~ubuntu18.04.4
  Version table:
 *** 1:3.26.4-0~ubuntu18.04.4 500
        500 http://fi.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     1:3.26.3-0ubuntu4 500

3) What you expected to happen
4) What happened instead

A directory containing any amount of files (may be just few, may be hundreds of files) is opened. Some file is right-clicked and Properties is selected, after which Nautilus hangs immediately.

It can be killed with "killall -9 nautilus" command, after which one must wait for short time before Nautilus can be started again.

If it is started too soon, it will not start, it just prints text: "Failed to register: Timeout was reached"

Thanks for your interest in helping to resolve this issue. In order to get to the bottom of this we need to figure out where the program is hanging. If you can follow the steps on https://wiki.ubuntu.com/Backtrace#Already_running_programs and attach the generated text file to this bug it would be of great help.

I noticed that RabbitVCS / checkerservice.py was the reason for hanging. After I removed the RabbitVCS installation, Nautilus doesn't hang any more.

Could this bug be moved to rabbitvcs-nautilus?
