[STR New]

In STR #4232 i attached the file
https://www.cups.org/strfiles/4232/0001-Correctly-call-DeleteDevice-when-using-colord-on-lin.patch

This did the following to fix printers being removed on RHEL and Fedora:

-  dbus_message_iter_append_basic(&args, DBUS_TYPE_STRING, &device_id);
+  dbus_message_iter_append_basic(&args, DBUS_TYPE_OBJECT_PATH,
&device_path);

In http://svn.easysw.com/public/cups/trunk@10761
7a7537e8-13f0-0310-91df-b6672ffda945 mike committed a fix that was
different:

-  dbus_message_iter_append_basic(&args, DBUS_TYPE_STRING, &device_id);
+  dbus_message_iter_append_basic(&args, DBUS_TYPE_OBJECT_PATH,
&device_id);

This causes a high profile crash in RHEL 7 which triggers the automatic
crash reporting service. The outcome is now a segfault of cupsd, rather
than the printer being removed. This will affect any Linux distribution
that ships colord and cups where the user tries to remove a print queue.

Thanks,

Richard.
