Almost certainly; the `line-move' function is chock full of special
code to deal with intangible characters, which in my experience breaks
often, and never _really_ works correctly. I don't really understand
the it that well, but I think the problem often involves hidden
newline characters.
If anyone's interested, here's a simple test-case that illustrates the
problem:
(with-current-buffer (get-buffer-create "*test*")
(insert "1: hello\n")
(insert (propertize "2: cruel\n" 'invisible t 'intangible t))
(insert "3: world\n")
(insert "4:\n"))
After evaluating that, go to the *test* buffer, and move around using
C-n & C-p. I can see the following bugs:
(1) If the cursor is in the first column, you can't move from line
"3:" to line "4:" using C-n (but C-p works all the way from the
end of the buffer to the beginning).
(2) If the cursor is in a different column, C-n seems to work
correctly on all lines, but C-p won't move from line "3:" to
line "1:" (it seems to work on all other line though).
