gdb shows segfault on reading passwd.db

From: Daniel Kehoe <kehoe_at_fortuity.com>

I've compiled and installed Subversion 1.1.3 on a Sun Cobalt Raq550 but
I'm getting a "Segmentation fault" error on use of "svnadmin create".

I've run gdb debug and found "svnadmin create" fails on an attempt to
open "/var/db/passwd.db". It shows "No such file or directory" but the
file *does* exist.

Is there a potential problem with different versions of that file or
Berkeley DB on this system?

Is there a configuration file I need to create?

I'd appreciate any help on resolving this issue. I've already scoured
the FAQ and the mailing list archives.

Here's the debug details.

[root /var]# which svnadmin
[root /var]# svnadmin create /var/subversion
