M-x load-library <RET> etags <RET>
M-: (tags-verify-table "any-file-not-tags") <RET>
It returns nil and leaves behind a buffer visiting the file, in Tags Table
mode. Not nice, but more or less as expected. Not a bug.
However, if you verify a (no tags) file already being visited in a buffer,
it returns nil and *leaves* the buffer in Tags Table mode!
Well, you'll say, "don't do that". Ok, except that you can do it by
accident, for example if you're using bs-show and happen to type "t" in the
wrong line.
Which, arguably, could be fixed in bs (though I think it's a bug in
etags.el, not bs.el), except that I don't think there's a
tags-table-buffer-p or equivalent to check that the buffer contains a Tags
Table. The way to test it seems to be `tags-verify-table'...
I had a similar issue recently (see bug#54133 [1]) though coming from
buffer-menu-mode. I would recommend filing a bug report, though the
upshot was that in some situations putting the buffer into
tags-table-mode is TRT, but making it harder to do by accident is also a
good thing.
