Tvheadend

Hello,

Just upgraded to TVH 4.3-448~g2f07ea089 and when trying to play one specific channel (via VLC with transcoding, or via WebUI with transcoding) the TVH crashes instantly.
Playing the same channel over Kodi (htsp) and VLC pass profile works without problems.
Other channels (the ones I tried so far) are not affected.

Using:
- WEBTV profile H264/AAC/Matroska transcoding profile
- MKV container (built in)
- video profile webtv-h264 (height 512, no HW acc, no deinterlace, 1Mbps bitrate)
- audio profile webtv-aac (aac, 64kbps bitrate)

If something else is needed please let me know.
Thank you.
