xine-thumbnailHang.patch

That a very annoying bug is represented for me on a Notebook and PC with Debian 11 at playing a video file (MP4 and MKV mostly) from a mounted MicroSD, when kaffeine terminated of playing the files after the second or third one and I cannot to demount the MicroSD due to its busy.

After learning the issue I see of creation a thumbnail for those video files through the function calls: ThumbnailProtocol::get() > ThumbCreator::create() > VideoCreator::create() >  xine_play(), and many hanged tdeio_thumbnail processes. That is, the hangs are performed in the xine_play() playing function.

LibXine is a familiar library that often hangs in different places and its updating from 1.2.10 to 1.2.13 doesn't resolve the problem, so using it in such functions is a bad decision. And due to the function is low priority one for me, I just disabled it in the function VideoCreator::create().

This patch is also VERY actual on 14.1.0 due to LibXine can hang even in GUI playing back of Kaffeine!!!
