Bug 472650

SUMMARY
Using Obsidian to click on mailto: links results in nothing in the case of Thunderbird being the mail client.

OBSERVED RESULT
Log "/usr/bin/xdg-email: line 619: thunderbird.desktop: command not found"

run_thunderbird()
{
    local THUNDERBIRD MAILTO NEWMAILTO TO CC BCC SUBJECT BODY ATTACH
    THUNDERBIRD="$1"

    else
        MAILTO=$(echo "$MAILTO" | sed 's/^/to=/' | sed 's/?/\&/')

I think what is going on here might be that because Thunderbird was installed as part of Rocky 9.2 distro there might be some sort of registration issue. Perhaps solved by creating a thunderbird.desktop file? Seems a bit odd if that is the case to rely on that when the program is installed to being within the menu system? 

Is this an error or a unmet requirement?
