[ubuntu-mono] [Bug 1769367] Re: Docky.exe assert failure: free(): invalid pointer

It is an additional report.

When I use Docklet's "Recent Documents" in Docky, "Docky" suddenly ends.
This is the same. However, in the past, ".crash" file was created, but
now ".crash" file is no longer created.

Instead, when I start "docky" from the terminal, a trace message is
displayed on the terminal. (#5)for details.

Title:
  Docky.exe assert failure: free(): invalid pointer

Status in docky package in Ubuntu:
  New

Bug description:
  Ubuntu 18.04 LTS (Japanese environment)

  Docky version: 2.2.1.1-1
  Kernel version: 4.15.0.20

  When I use docklet's "Recent Documents" at "Docky", suddenly "Docky"
  will end. (Crash)

  Since I can not find known problems in automatic reporting, I reported
  it manually.

  In the previous time,
  A failure occurred with the following installation method.
  $ sudo apt update
  $ sudo apt install docky

  This has been reported.

  1. I right click on "Recent Documents".
  2. A list of document creation history appears.
  3. I clicked one from the list.
  4. The file opens in the "gedit" application.
  5. After that, we do not accept any input.
  I can not take screenshots.
  6. After a while, the dock suddenly disappeared from the desktop screen.
  7. After a while, the error report screen opened.
  "Application Docky suddenly ended."

  This time,
  I registered "ppa" and installed "docky".
  Since the version is the same, the same failure occurs.

  This report is about the trouble that occurred at that time.
  I sent it for troubleshooting reference.

  $ sudo apt --purge remove docky
  $ sudo apt autoremove

  dpkg: Warning: During deletion of libmono-security4.0-cil, it could not be deleted because the directory '/usr/lib/mono' is not empty

  $ sudo apt-add-repository ppa:docky-core/stable

  Now, since "bionic" is not supported, I corrected it.
  http://ppa.launchpad.net/docky-core/stable/ubuntu bionic main
  ↓
  http://ppa.launchpad.net/docky-core/stable/ubuntu artful main

  $ sudo apt update
  $ sudo apt upgrade
  $ sudo apt install docky
  ↓
  docky is already the latest version (2.2.1.1-1).

  Since the version is the same, the same failure occurs.
