polybar: segmentation fault when `pin-workspaces = false` in xworkspaces module

Checklist

• I have read the appropriate section in the contributing guidelines
• I believe this issue is a problem with polybar itself and not a misconfiguration on my part.
• I have searched for other open and closed issues that may have already reported this problem.
• I have checked the known issues page for this problem.

Describe the bug

removing or setting pin-workspaces = false results in segmentation fault

Was it working before?

• Did you also experience this bug in an earlier version of polybar (yes/no/don’t know)?
• If no, what was the last version where this worked correctly? not to my knowledge

To Reproduce

[module/workspaces]
type = internal/xworkspaces

pin-workspaces = false

[bar/main]
modules-left = workspaces
