Title:
Using Zenity in conjuntion with workspace switch command causes
segmentation fault in budgie-wm
Status in zenity package in Ubuntu:
New
Bug description:
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
