Following bash script interprets text in an image file and writes to a .txt file.
#!/usr/bin/env bash
LD_LIBRARY_PATH="/usr/local/lib"
export LD_LIBRARY_PATH
/usr/local/bin/tesseract /home/martin/work/textpic.png /home/martin/work/tesseract-out
When I run it from the terminal the tesseract-out.txt is created, but when I run it via custom keyboard shortcut nothing is written. I have ensured that the correct script is run by putting echo "test" > /home/martin/work/test.txt in it, which creates the file.
I have run sudo chmod 777 on tesseract in case it was some permission issue.
I have an inkling that tesseract needs some lib files which are not in paths when the script is run by shortcut, so I put these lines at the top of my script file (I know that some of the lib files it needs are in /usr/local/lib):
LD_LIBRARY_PATH="/usr/local/lib"
export LD_LIBRARY_PATH
But it did not do the the trick. How can I debug what is going wrong? If I could obtain some kind of error message somehow, that would go a long way.

The keyboard-shortcuts manager I use is the standard GUI one in Mint 18. Might be I could use something else to get a better error message?
EDIT:
I verified that all needed libs are in path by putting /sbin/ldconfig -N -v $(sed 's/:/ /g' <<< $LD_LIBRARY_PATH) > /home/martin/work/libs-in-path.txt at the bottom of my script and crosschecking the output against readelf -d /usr/local/bin/tesseract | grep NEEDED.
