BTW: I've tried to enable IMAGE_GEN_DEBUGFS for first time as described in manual:
  Build sysroot paths are now removed from debug symbol files. Removing these paths means that remote GDB using an unstripped build system sysroot will no longer work (although this was never documented to work). The supported method to accomplish something similar is to set IMAGE_GEN_DEBUGFS to "1", which will generate a companion debug image containing unstripped binaries and associated debug sources alongside the image.

and it fails with ugly exception, because IMAGE_FSTYPES_DEBUGFS isn't set by default.

It should either be mentioned in the manual or there should be some sane default for it.

meta/conf/local.conf.sample.extended shows example how to set it next to IMAGE_GEN_DEBUGFS,
people reading this sample may notice it, but the comment also says:
  If IMAGE_FSTYPES_DEBUGFS is not defined, it defaults to IMAGE_FSTYPES.
which isn't true for some reason in my setup, looking at the code I don't see where it is supposed
to default to IMAGE_FSTYPES

    if d.getVar('IMAGE_GEN_DEBUGFS', True) == "1":
        debugfs_fstypes = d.getVar('IMAGE_FSTYPES_DEBUGFS', True).split()
        for t in debugfs_fstypes:
            alltypes.append("debugfs_" + t)

Maybe the author meant that IMAGE_FSTYPES variable is set to IMAGE_FSTYPES_DEBUGFS
only when IMAGE_FSTYPES_DEBUGFS is set, but that still leaves that split()
causing parse failure.

    debugfs_image_fstypes = d.getVar('IMAGE_FSTYPES_DEBUGFS', True)
    if debugfs_image_fstypes:
        d.setVar('IMAGE_FSTYPES', debugfs_image_fstypes)
