gksu -u root segfault (dapper)

[Luis Mondesi]

When explicitly setting the user to root in gksu, the application segfaults.

Example:

$> gksu echo foo
foo

$> gksu -u root echo foo
Segmentation fault

I can reproduce this.

Works fine for me in dapper, can you try and get a backtrace?

[Luis Mondesi (lemsx1)]

(gdb) run --disable-grab -u root echo foo

Seem related to the new theme engine?

gksu version 1.3.6-1ubuntu13, gtk2-engines-ubuntulooks version 0.9.5-1.

[Ming Hua (minghua)]

Nah. Also reproducible with clearlooks theme.

[Dennis Kaarsemaker (dennis)]

Ming, yours looks like an error in the new Ubuntu theme - could you try
with another theme set. Luis, please try that too.

Are you both using the latest version of ubuntulooks?

[Luis Mondesi (lemsx1)]

Dennis,

I'm using the new version of the theme for controls, indeed. (metacity and icons are different -- milk and gartoon respectively)

[Luis Mondesi (lemsx1)]

tried Nuvola theme. same error

[Luis Mondesi (lemsx1)]

the segfault happens exactly at this line:

dialog = g_object_new (GKSUUI_TYPE_DIALOG,
                        "type", GTK_WINDOW_POPUP,
                        NULL);

in gksu.c around line number 1215 or so

Seb, you're the resident gnome GURU - what do you think?

[Michael Vogt (mvo)]

Thanks for your bugreport.

I tried this on two different dapper machines (both up-to-date) and wasn't able to reproduce it. Is it still a problem?

Thanks,
 Michael

[Luis Mondesi (lemsx1)]

using the latest version of dapper's gksu worked. please close.

[Dennis Kaarsemaker (dennis)]

Good to hear, thanks
