Crashes when searching after binding with "behave" #169

Open lamby opened 7 years ago

lamby commented 7 years ago

Via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=858221:

I'm trying to bind a "search" command for another window when (say) an
MPlayer window is focused:

 $ xdotool search --name MPlayer behave %@ focus \
     search --name . getwindowname

However, xdotool segfaults upon focusing Mplayer:

(gdb) run search --name MPlayer behave %@ focus search --name . getwindowname
Starting program: /usr/bin/xdotool search --name MPlayer behave %@ focus search --name . getwindowname
