Often crashing after upgrading to Ubuntu 13.10

[Sadi Yumuşak]

I've been happily using medit as my favorite text editor for several years ...until I upgraded to Ubuntu 13.10 yesterday, after which it began crashing instantly with error message "Segmentation fault (core dumped)" displayed when launched from Terminal.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

If you run under admin using sudo, it will not crash!

Try running medit in terminal (as a standard user). The attempt to add property MooEditConfig::indent-wideth fails with a segmentation fault (see Attachment)

Mostafa Najafi (najafiyazdi-m) is right. If medit is ran with sudo, it doesn't crash.
I like medit so much that I arranged a temporary solution for myself.

- I have installed Main Menu with :
sudo apt-get install alacarte
- Then I opened Main Menu, navigated to Accessories, then "medit" menu item. Clicked Properties.
- In the "Command" field, I found the text "medit %F" (without quotes). I have added sudo before it, making it:
sudo medit %F
- Clicked OK and quit Main Menu.

Now medit doesn't crash when I open it from dash. After opening it from dash I have right-clicked on the launcher icon of medit and clicked Lock to Launcher. Now the launcher shortcut works ok. (I haven't used Software center to install medit, so I had to manually add the icon to Launcher. You may not need to do this.) This solution also works when you open a file with nautilus right click menu. Cool!

This is not a permanent solution, I know. But it lets you use medit until the bug is resolved.

I have debugged the crash on my Ubuntu using latest code from
hg clone https://<email address hidden>/medit/medit

I have found that crash occurs in the callback update_recent_list_visibility

So for now I closed the initialization of this callback - I do not know what side effects this will cause.

In function void
_moo_encodings_menu_action_set_current (GtkAction *gtkaction,
                                        const char *enc_name)
 I have cahnged internal if to

        if (action->cur_item && !action->update_idle)
        {
        /*
            action->update_idle = g_idle_add_full (G_PRIORITY_DEFAULT_IDLE + 1,
                                                   (GSourceFunc) update_recent_list_visibility,
                                                   action, NULL);
                                                   */
        }

So far medit starts without crash.
I hope somebody who knows what this callback suppose to do will find a reason for the crash and fix bug properly

The solution I've found is this ;-)
