Comment (by Cigaes):

 I do not think this is absolutely necessary here: if you know how
 subtitles and seeking work, reading the title of the ticket is enough to
 guess what and why, the only problem in reproducing it is finding files
 layound around on one's hard drive.

 The hard part is to devise a clean way of fixing the problem.

 Other temporary workarounds: {{{-ss}}} as output option (slower before the
 start of encoding), or {{{-copyts}}} to keep the timestamps (but it will
 require {{{setpts}}} to reset the timestamps afterwards, or it will show
 in the output file).
