dovecot crashes if you don't explicitly set "trash_priority" on all namespace mailboxes.

Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007f6af06b4563 in trash_try_mailbox (error_r=0x7ffcf37077b8, box_name=0x56384813f980 "Drafts", ns=0x5638481423b0) at trash-plugin.c:582 (gdb) print trash_set $1 = (const struct trash_settings *) 0x0

unsigned int trash_priority = trash_set->trash_priority; // ^^^^^^^^^ SIGSEGV if NULL

here is my configuration, to stop it from crashing uncomment the two "trash_priority = 0". cheers
