i3lock_away.py: "pidof: can't read from #######/stat"

[Scary-Guy]

Bug summary:

While using Weechat the terminal running it will sometimes throw an error:
"pidof: can't read from #######/stat"

Steps to reproduce:

1. Install the script.
   2. Run Weechat for a really long time.

Current behavior:

Error thrown in terminal shifting the TUI up three lines.

Expected behavior:

No error thrown in terminal

Suggested solutions:

Either of these makes the error go away:
Restarting Weechat
Make window (if ran in a window) fullscreen then back, or vice versa.

Additional information:

It's really more of a minor annoyance than anything.
This has been going on for YEARS across different versions of Debian and LMDE versions 4/5.

• WeeChat version: 3.8
• OS, distribution and version: Regolith Linux 2 (Ubuntu)
• Terminal: Terminator
• Terminal multiplexer (screen/tmux/…/none): None

##Note:
@flashcode says that the cause is the i3lock_away.py script. As I don't know anything about coding I'm going to take their word for it. As far as I can tell though the script is working as intended despite this.
