Task: Compare two saved and currently opened files via external tool. External tool should launch kompare with previously mentioned files as arguments (in ex. kompare $file1 $file2)

%URLS macro should resolve itself to list of space separated urls to saved currently opened files, in ex. (as I understand it) file:///tmp/file1.txt file:///tmp/file2.txt

Plan/how to reproduce: Create external tool with fields filled as follows:

label: kompare
script: kompare %URLS 
exacutable: kompare
Mime types :   // blank
save:   //blank
command line name: kompare

Expected behaviour: 

while having 2 saved files opened and selecting 'kompare' external tool, kompare is launched with arguments representing those files.

What is wrong?

%URLS macro is not resolved. Instead when I select my created external tool, kompare is launched but returns error: 

The URL file:///home/tlisiecki/%25URLS does not exist on your system.

I also tried kompare "%URLS", kompare %urls, kompare "%urls" but still no luck


Loaded plugins: 
-Terminal tool
-find in files tool view
-external tools

I also checked %URL macro which should give url to currently edited file, and it worked ok
The script was : script: kompare %URL /tmp/xorg.conf, where %URL was resolved to file:///etc/X11/xorg.conf
