@Till, the error pointed out by valgrind happend when I manually start
cups-browsed at any time during the session, it's not a shutdown problem
==5706== Invalid write of size 8
==5706== at 0x124791: UnknownInlinedFun (string_fortified.h:71)
==5706== by 0x124791: update_cups_queues (cups-browsed.c:7381)
The error basically means that in cups-browsed.c at line 7381 it tries
to incorrect use a variable
the corresponding line in the code is
memset(deleted_master, 0, sizeof(remote_printer_t));
but it's defined as
static remote_printer_t *deleted_master = NULL;
but you don't seem to allocate an actual array there where you should?
Let me know if you still need the log but I think the code there is just wrong?
