A comment suggests that tvb_get_ptr() was used previously, so this might be a botched rework of that code?
Currently neither linelen nor next_offset are used in that function after assignment, so there's clearly something amiss here. To me, it looks like "linelen = tvb_find_line_end(tvb, 0, -1, &next_offset, FALSE);" is just superfluous, unneeded code that was probably due to "copy-and-paste" or rework by the original author, as the code has been that way since day 1.
