Using Zenity in conjuntion with workspace switch command causes segmentation fault in budgie-wm

[Tom Holmes]

Ubuntu Release: 17.04 with Budgie-Remix installed
Zenity Version: 3.24.0-0ubuntu1
Wmctrl Version: 1.07-7

When using wmctrl or zenity separately, they both work fine. Put them together however and budgie window manager crashes with a segmentation fault.

This happens using both "wmctrl -s 0" and "xdotool set_desktop 0". They work fine on their own but not in combination with Zenity.

Expected Result: Running the script from workspace 0 switches to workspace 3 and opens firefox. Running again prompts the user to ask if they're sure, then switches back to workspace 0 if they click yes.

Actual Result: Running the script from workspace 0 switches to workspace 3 and opens firefox. Running again prompts the user to ask if they're sure, then budgie window manager crashes with a segmentation fault if they click yes.

Code to replicate:

    #!/bin/bash

    desktop=$(xdotool get_desktop) #Get current workspace id

    if [ "${desktop}" -eq 0 ] #If workspace == 0
    then
      wmctrl -s 3 #Switch to workspace 3
      firefox --new-window "http://www.reddit.com"
    else
        zenity --question --title "Switch Workspace?" --text "Are you sure you wish to return to previous workspace?"
        if ! $? #If response Yes
        then
          wmctrl -s 0 #Switch back
        else
          notify-send "Operation Aborted" "User canceled workspace return."
        fi
    fi

Example of working code when `wmctrl` command is used alone:

    #!/bin/bash

    desktop=$(xdotool get_desktop) #Get current workspace id

    if [ "${desktop}" -eq 0 ] #If workspace == 0
    then
      wmctrl -s 3 #Switch to workspace 3
      firefox --new-window "http://www.reddit.com"
    else
      wmctrl -s 0 #Switch back
    fi
