[Bug 70223] Re: Internal data flow error.

[Aleksander Kamil Modzelewski]

And here too. It seems that it's not related to click speed - it just
doesn't happen once in few runs/plays. I just click ok on the error
message, then click play - and it plays. Or not. Some subtitle
types/files seem to be more prone to problems than others. A race
condition of some kind?
