Hello,
Today is Sunday and as I expected, xscreensaver is working fine again. It confirms the weekly pattern failure!
After compiling xscreensaver to include debugging symbols I have been trying to use
gdb to discover where it fails but it has been impossible for me. It appears than
xscreensaver calls xscreensaver-auth to unlock the screen and it crashes there. I
do not know how to inspect that scenario under gdb. If I load xscreensaver in GDB
and it calls xscreensaver-auth and crashes there, I do not see anything. I do not
have enough expertise to do it properly. Any hints will be appreciated.
From xscreensaver log:

For me there is absolutely no problem in running xscreensaver with "C" locale, but it is
interesting to understand where it fails. I am thinking that perhaps the author is the
only person that may understand it better, but in his WEB page he tells that:
"If you are reporting a bug in any version earlier than 6.16 then you are probably
wasting your time and mine. So please, I implore you, upgrade first. "
NetBSD uses 6.15 version, which is far more modern than 6.09 in Debian Trixie, even in Debian Unstable!
I do not want to try to manually change to 6.16 in pkgsrc, there are patches involved and
I do not have enough expertise to do that and I will enter in another problem.
Thanks.
Ramiro.
