gdb /path/to/svn svn.core is what you want. But for that to be useful
you need a svn executable built with debugging info. This can be done by
building the port with CFLAGS having the '-g' option and STRIP set to
null, so you don't lose that info while installing.

(deinstall svn first)
e.g.: cd /usr/ports/devel/subversion && env CFLAGS="-g" STRIP="" make
install

Then try to reproduce the error and run gdb. Once in gdb use the command
'bt' to get a backtrace.

Cheers,
