xrdb does not list workspaces

[cedrak]

After upgrading to newest Regolith Desktop Super + ` keybinding stopped working. After fast investigation I found out that i3-next-workspace errors out with following error:

$ i3-next-workspace
Traceback (most recent call last):
  File "/usr/bin/i3-next-workspace", line 38, in <module>
    startnum = min(mapping_names.keys())
ValueError: min() arg is an empty sequence

The problem seems to be with xrdb -query call which does not list anything that would match regex re.search("^i3-wm\.workspace\...\.name:",line):

$ xrdb -query | grep workspace
i3-wm.bar.workspace.active.background.color:	#9A9996
i3-wm.bar.workspace.active.border.color:	#9A9996
