[maemo-developers] Segmentation fault with the latest microb-engine

[From: Zhihai Wang]

Hi,

I'm not good at gdb, and I'm just learning how to debug.

Following is the trace I got, if this is not enough, I would like to collect
more trace for you:

js_status_cb
js_status_cb
location_changed_cb
open_uri_cb http://www.google.com/
load_started_cb
js_status_cb
js_status_cb
location_changed_cb
net_state_change_cb 196612
progress_change_cb cur 1199 max 2547
title_changed_cb
progress_change_cb cur 2547 max 2547
net_state_change_cb 65552

Program received signal SIGSEGV, Segmentation fault.
