crash could be at the gnome-app-install patch, marking it as confirmed since the backtrace is completed.

[Sense Egbert Hofstede (sense)]

I've reported this bug upstream and am marking it as Triaged since the work of Bug Control here is done so far. We'll now wait until someone with more understanding of the traces responds.
Thank you for reporting this bug!

This is not an upstream issue but a problem in a patch from ubuntu (82_gnome-app-install.patch):
+void launch_gnome_app_install_mimetype(GdkScreen *screen,
+ NautilusFile *file,
+ char *uri) {
+ char *qmimetype, *quri, *qduri, *command;
+ if (!screen)
+ screen = gdk_display_get_default_screen(gdk_display_get_default ());
+
+ qmimetype = g_shell_quote (nautilus_file_info_get_mime_type (file));
+ quri = g_shell_quote (uri);
+ command = g_strconcat("gnome-app-install --mime-type=",
+ qmimetype, " ", quri,
+ (char*)0 /* NB NULL is wrong */);
+ g_free (qmimetype);
+ g_free (quri);
+ g_free (qduri);
+
+ //eel_gnome_shell_execute_on_screen (command, screen);
+ gdk_spawn_command_line_on_screen (screen, command, NULL);
+ g_free (command);
+}

Probably best to check NULL for nautilus_file_info_get_mime_type () as it could, but very very rarely return NULL:
char *
nautilus_file_get_mime_type (NautilusFile *file)
{
 if (file != NULL) {
  g_return_val_if_fail (NAUTILUS_IS_FILE (file), NULL);
  if (file->details->mime_type != NULL) {
   return g_strdup (eel_ref_str_peek (file->details->mime_type));
  }
 }
 return g_strdup ("application/octet-stream");
}

(Note, nautilus_file_info_get_mime_type() just calls the interface function)

do you have an easy example to trigger the bug?

[Sebastien Bacher (seb128)]

the bug has been get duplicates/comments for 7 years, assuming it's obsolete and closing, you should open a new report if you still get that issue with a current version
