[DCP-o-matic] Bug report: Long freeze/hang at 99%

Hi, Im using the latest version of DCP-o-matic and I'm experiencing freezing/long hangs at 99%. The clip I'm transcoding is 2h long and the only way I got it to work was to trim the clip to three different parts. It still freezes at 99% but if I wait 5 minutes the "computing image test" starts. I waited over 30 minutes twice when trying to transcode the whole clip. I'm using the latest Mac version, I tried both the latest (4th of December) and the one before and both of them got the same problem. Mvh Linus
