Bug 79200 – Evolution 2.0.3 hangs after setting timezone in Setup Assistant

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Tim Hentenaar 2005-01-23 05:15:22 UTC]

Evolution 2.0.3 hangs in prepare_importer_page() on gnome-2.8.1. 

Using gdb, I traced it down to a single block of code (e-shell-startup-wizard.c):

dialog = gtk_message_dialog_new (NULL, 0, GTK_MESSAGE_INFO,
					 GTK_BUTTONS_NONE,
                            _("Please wait...\nScanning for existing setups"));
#if !GTK_CHECK_VERSION (2,4,0)
	gtk_dialog_set_has_separator (GTK_DIALOG (dialog), FALSE);
#endif
	e_make_widget_backing_stored (dialog);
        gtk_widget_show_all (dialog);            /* We'll hang here */ 
        gtk_widget_show_now (dialog);            /* Or here         */
        gtk_widget_queue_draw (dialog);          /* Maybe here too  */
        gdk_flush (); 

        while (gtk_events_pending ()) {
	      gtk_main_iteration ();
        }

The real problem is that gtk_widget_show_all(), etc. are calling gtk_dialog_run() because dialog is a GtkDialog. Since a "response" signal is never being sent to the dialog, the program gets thrown into a recursive loop. 


Reproducible: Always
Steps to Reproduce:
1. Emerge the evolution 2.0.3 package 
2. Go through the setup assistant
3. Watch it freeze

Actual Results:  
The UI locked up

Expected Results:  
The software should have displayed a dialog

Patch to remedy this bug

This patch works by using a window instead of a dialog for the same purpose,
thus bypassing the gtk_dialog_run() recursive blocking loop.

Tim, could you please post your work upstream on http://bugzilla.ximian.com/show_bug.cgi?id=71552

Good work, it'd be great to get this fixed upstream.

[Comment 4 Tim Hentenaar 2005-01-24 06:30:35 UTC]

Thanks.
I posted the patch on the Ximian bugzilla at the URL you gave. I just hope that it gets at least added to portage before too long to save more people a headache. :P

[Comment 5 Adam Bowers 2005-01-24 10:50:15 UTC]

New to patching.  How would I apply the patch and then recompile?

[Comment 6 Tim Hentenaar 2005-01-24 11:28:22 UTC]

Adam,

Here's a quick procedure to get you up and running:

First, clear out the portage temporary work directories. Doing this periodically can free up some disk space too.

# rm -rf /var/tmp/portage/*
# rm -rf /usr/portage/distfiles/*

Now, tell portage to download and unpack the source archive.

# ebuild /usr/portage/mail-client/evolution/evolution-2.0.3.ebuild fetch unpack 

Apply the patch

# cd /var/tmp/portage/evolution-2.0.3/work
# patch -p0 < /path/to/the/patch

Tell portage to compile and install (as well as do anything that needs to be done postinstall.)

# ebuild /usr/portage/mail-client/evolution/evolution-2.0.3.ebuild compile install qmerge config

Regards,

Tim Hentenaar

Found the bug report upstream.  This is a bug with >=GTK+2.6 .  The proper way to fix this is to apply the patch in bug #80262 .

[Comment 8 Saleem Abdulrasool (RETIRED) 2005-01-31 15:02:18 UTC]

*** Bug 78539 has been marked as a duplicate of this bug. ***

[Comment 9 Joe McCann (RETIRED) 2005-02-02 22:58:09 UTC]

This is fixed with gtk+-2.6.1-r2
