In opening an email address with mailto in Chromium three backslashes appear in front of it in the recipient field that I have to manually remove before sending. I use Xubuntu 15.04, and Chromium opens Thunderbird with the mailto address using xdg-open, which I set to detect the default desktop as Gnome for compatibility reasons. How would I fix it so these back slashes don't appear in the first place? Attached is a screenshot. Thanks! :D
