Word-completion crashes with BadAlloc

[Adam Olsen]

1. Download a copy of http://svn.openttd.org/trunk/src/lang/english.txt
2. open in scribes and click on the first blank line
3. type in STR_
4. Crash is almost immediate.

Console output:

$ scribes english.txt
$ /usr/lib/pymodules/python2.7/SCRIBES/Main.py:10: Warning: g_object_set_qdata: assertion `G_IS_OBJECT (object)' failed
  main()
/usr/lib/scribes/GenericPlugins/WordCompletion/GUI/Window.py:34: GtkWarning: Native Windows wider or taller than 65535 pixels are not supported
  self.__window.show_all()
The program 'Scribes' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 5767 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.)

Thanks. Loving the editor.

Oh, and ctrl-shift-alt-c does avoid the crash.

Interesting, I can't reproduce this problem at all. Looks like a bug in X. I'll test again on a Linux Mint box I have and report back.

BTW, just to add that that g_object_set_qdata warning is https://bugzilla.gnome.org/show_bug.cgi?id=661155 which has been fixed in git.gnome.org repository (http://git.gnome.org/browse/pygobject/commit/?h=pygobject-2-28&id=42d871eb0b08ee6d55e95cc7e4b90844919555b9), but new release of pygobject has not been made yet.
