Public bug reported:
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
