Public bug reported:
Binary package hint: zenity
displaying extremely long error causes the window manager to crash.
if the keyboard doesn't respond , login in tty and run "compiz&" .
test case :
emanuel@emanuel-desktop:~$ zenity --error --text=`python -c "print 'A'*115000"`
(zenity:8369): Gdk-WARNING **: Native Windows wider or taller than 65535 pixels
are not supported
The program 'zenity' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
(Details: serial 266 error_code 158 request_code 148 minor_code 8)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
sometimes it print other messages :
emanuel@emanuel-desktop:~$ zenity --error --text=`python -c "print
'A'*115000"`
(zenity:8406): Gdk-WARNING **: Native Windows wider or taller than 65535 pixels
are not supported
zenity: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.
** Affects: zenity (Ubuntu)
Importance: Undecided
Status: New
