I'm on Debian testing with package printer-driver-cups-pdf version 3.0.1-14.
I get broken output file names as well, and I think it is an upstream bug.
Here is my configuration as dumped by cups-pdf:

Thu Mar 9 14:50:11 2023 [DEBUG] *** End of Configuration ***
------------------------------ snip ------------------------------
A few lines later in the log file I get these really suspicious entries:
------------------------------ snip ------------------------------
Thu Mar 9 14:50:11 2023 [DEBUG] found title in ps code: cups-pdf.c
idt/tmp/transfer/print
Thu Mar 9 14:50:11 2023 [DEBUG] found end of postscript code: %%EOF
------------------------------ snip ------------------------------
Note that newline ("cups-pdf.c***\n***idt/tmp/transfer/print") is part of
the first log line!
So IMHO there is something wrong with this block from cups-pdf.c:
------------------------------ snip ------------------------------
if (sscanf(buffer, "%%%%Title: %"TBUFSIZE"c", title)==1) {
log_event(CPDEBUG, "found title in ps code: %s", title);
is_title=1;
}
------------------------------ snip ------------------------------
Can it be that the result in variable title needs to be zero-terminated?
