Char % added to destination folder

[pdelteil]

I'm running the script like this:

./save_page_as -d /tmp -b chromium-browser --load-wait-time 1.5 --save-wait-time 3 "$URL"

Sometimes, while the script is saving the file, it shows &tmp on the save dialog. Sometimes it works correctly. Im also using another script to call save_page_as with several different urls.

What could be the problem?
