Yes, I suspected to deliver the default ls-R might fix
the problem if this was the fresh install, but this was
not the case so it is trivially irrelevent.

And this was an upgrading problem then I've no idea or
rather there are too many possibilities, I guess.

disk might be full at some instance?
some particular debconf settings on lsr-perms etc. and
some action?
ohter packages (possibly wrong) action on ls-R?

And is there any overlooked problem in the recent patch
to mktexlsr?
