Comment 5 for bug 1795668

This change just landed in bionic, and now my raw.thumbnailer does not work anymore. :(

raw.thumbnailer content:

[Thumbnailer Entry]
Exec=/usr/local/bin/raw-thumbnailer.sh %s %u %o
MimeType=image/x-canon-cr2;image/x-cr2;

raw-thumbnailer.sh content:

#! /bin/bash
/usr/bin/ufraw-batch --embedded-image --out-type=png --size=$1 $2 --overwrite --silent --output=$3

How can I fix this? Now I can't get any debug output from my shell script anymore.
