Conesearch crashing when querying web-encoded url

[chbrandt]

Email from user:

I installed EADA from the source files on github using the command
"python setup.py install". I have Ubuntu 18.04LTS (64bit) and I use
python 2.7.17. However, when I launch conesearch I get this error:

conesearch --db /home/dell/VOU_Blazars-master/bin/cats1.ini --catalog
5BZCat --ra 194.046 --dec -5.789 --radius 0.5 --runit arcmin --columns
default -o 5bzcat.1.csv

Have you seen this error before? Do you know how I could fix this?
