$ docky
↓　(Continued, the second part)

Cairo.Surface is leaking, programmer is missing a call to Dispose
Set MONO_CAIRO_DEBUG_DISPOSE to track allocation traces

=== Dock finished booting ===
Here, when I use docklet's "Recent Documents", suddenly "Docky" crashes.

free(): invalid pointer

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)

  The following URL address was displayed, but it can not be found.
  DuplicateOf
  https://bugs.launchpad.net/bugs/1758268

  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

  dpkg: Warning: During deletion of libmono-security4.0-cil, it could

  $ 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.
