Hmm.  I don't get 100% cpu time when i run that.  I also am running gnome 2.22 on 32-bit.

Re: zenity takes 100% CPU Time

I have this same issue!!11

Don't ask me why though. It only happens when I use --notification...

Other icons (ie alert types) seem to work fine here.

Windows was made for looking at success from a distance through a wall of oversimplicity. Linux removes the wall, so you can just walk up to success and make it your own.

Re: zenity takes 100% CPU Time

I GOT IT... I think.

zenity --notification actually calls libnotify! I was trying out a script and suddenly realized something, because by chance dbus decided to take a break. Take a look at these two code fragments.

$ zenity --info --text "hello"
$ _

$ zenity --notification --text "hello"
libnotify-Message: Unable to get session bus: Failed to connect to socket /tmp/dbus-jmMdFXbznS: Connection refused
<hang>
<100% CPU usage>

I've figured out why: it's basic socket programming gone wrong. The notification part of zenity calls libnotify, tries to connect to libnotify's socket, and fails, using 100% CPU waiting for the connection to... end a stream that never started.

A possible solution is to just use notify-send.

notify-send works, but requires notification-daemon
