tsMuseR crashing

[Selur]

Haven't changed anything regarding tsMuxeR for ages.
The tsMuxeR meta file (/home/inigo/BDR/Spider-Man_Homecoming_t06_21_04_08_5310__08.meta):

MUXOPT --no-pcr-on-video-pid --new-audio-pes --blu-ray --label="SPIDER-MAN_HOMECOMING_T06" --vbr --vbv-len=500 --custom-chapters=00:00:00;00:05:33;00:14:24;00:20:50;00:26:19;00:36:27;00:46:03;00:54:40;01:05:10;01:12:03;01:20:19;01:29:41;01:36:56;01:44:44;01:50:31;01:57:53
V_MPEG4/ISO/AVC, "/home/inigo/BDR/21_04_08_5310_05.264", fps=23.976, ar=1:1 (Square), lang=eng

A_DTS, "/home/inigo/BDR/iId_1_aid_0_lang_es_21_04_08_5310_01.dts"
S_HDMV/PGS, "/home/inigo/BDR/Spider-Man_Homecoming_t06_id_3_lang_es_default.sup",fps=23.976, lang=spa

looks fine to me and the tsMuxeR call itself also doesn't look strange in any way:

/usr/bin/tsMuxeR" "/home/inigo/BDR/Spider-Man_Homecoming_t06_21_04_08_5310__08.meta" "/home/inigo/BDR/Spider-Man_Homecoming_t06"

Hybrid assumes that after that call there should be a file callend '/home/inigo/BDR/Spider-Man_Homecoming_t06.m2ts', but since that isn't the case it aborts.

-> What output do you get when you call the last call?
