The attached example program (by Colin Leroy) passes a string
with a long "word" to gtk_widget_set_tooltip_text() which causes
a crash when the tooltip is supposed to be shown.
(gdb) r --sync

[New LWP 101212]
[New Thread 805407400 (LWP 101212/initial thread)]
(long_tooltip_crash:65109): Gdk-WARNING **: Native Windows wider or taller than 65535 pixels are not supported
Gdk-ERROR **: The program 'long_tooltip_crash' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
(Details: serial 725 error_code 11 request_code 53 minor_code 0)
(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.)

Program received signal SIGABRT, Aborted.

I'm using GTK+ 2.22.1.
From the documentation at:
http://developer.gimp.org/api/2.0/gtk/GtkWidget.html#gtk-widget-set-tooltip-text
the expected behaviour isn't clear to me.
Is the crash a bug, or are applications supposed to somehow
verify that the tooltip text can't reach the limit mentioned
in the warning (or any other limits)?
Thanks
Fabian
