[Message part 1 (text/plain, inline)]

Emacs 24 (from https://launchpad.net/~cassou/+archive/emacs) on Ubuntu 
11.10 with auto-complete package http://cx4a.org/software/auto-complete/ 
installed from git https://github.com/m2ym/auto-complete

Crashes seemingly randomly when displaying the auto-complete pop-up 
window but always at the same location - see attached gdb bt full backtrace.

I am not able to reliably reproduce this (as I said above it seems 
random), but it seems to happen a few times every day and always when 
showing the pop-up window.

The following is my auto-complete config

;; auto-complete mode
(add-to-list 'load-path (expand-file-name 
"~/.emacs.d/vendor/auto-complete"))
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories 
"~/.emacs.d/vendor/auto-complete/dict")
(ac-config-default)
(setq ac-auto-start 1) ; make autostart after entering a single character
(setq ac-auto-show-menu (+ ac-delay 0.1)) ; show menu after 100ms
;; quick help has to be after menu so again set to 100ms more
(setq ac-quick-help-delay (+ ac-auto-show-menu 0.1))
