[Bug]: segmentation fault on fresh boot

[IfGremlinThen]

What happened?

I was able to install and customize conky with relatively little effort on two separate computers and in doing so I closed and relaunched conky several times. On a fresh boot, however, I receive this error when launching the installed .deb package from the Terminal:

conky: desktop window (2800010) is subwindow of root window (782)
conky: window type - desktop
conky: drawing to created window (0x4600002)
conky: drawing to double buffer
Segmentation fault (core dumped)

The .deb package was a little older so I uninstalled it, downloaded the latest .appimage and attempted to execute that, however I receive the same error with that as well. Conky simply does not boot at launch even if I set it to.

I am currently running it on an ASUS laptop under Linux Mint: Debian Edition 6 (Beta), and will test it out on a desktop Linux Mint 21.2 when I have the opportunity.

Version

1.18.3/1.19.4

Which OS/distro are you seeing the problem on?

Linux (other)

[IfGremlinThen]

I do not appear to experience this on Mint 21.2.

EDIT: I still experience this on Linux Mint: Debian Edition 6.

UPDATE:

This is potentially an issue with piping the bluetoothctl paired-devices command into awk instead of grep. Requires some further testing.

[IfGremlinThen]

I figured out the issue. Linux Mint: Debian Edition 6 runs bluetoothctl 5.66, whereas Linux Mint 21.2 runs bluetoothctl 5.64. There seems to be a discrepancy between these versions in which the paired-devices argument appears to have become deprecated.

The following code accomplished the same task in both versions of Mint:

${exec bluetoothctl info | awk -F 'Name: ' '/Name:/ {print $2}'}
