[webkit-gtk] Accessing the page load progress

[Andrew Wood]

So I now have a callback function registered on that signal which 
contains the single line:

gtk_progress_bar_set_fraction(GTK_PROGRESS_BAR(progressbar),webkit_web_view_get_progress(WEBKIT_WEB_VIEW 
(gtkwebview)));

But I get periodic crashes when it runs (seg faults).  If I disable the 
signal handler I dont get them.

Without knowing much about the internals of WebKit I dont really 
understand whats going on here.

The only insight I can give is that it seems to always occur immediately 
after the signal handler returns but as I say its only once in a blue moon.

If anyone can give me a clue as to whats wrong here Id be very grateful.

Thanks
