Under these circumstances, I question whether svn-push.c is the right
course to follow – it is more of a toy than an actual tool, as evidenced
by the fact that it makes no attempt whatsoever to copy log messages
(replacing them with “Hello, world!” !!!), authors, or dates.

You really need to build subversion with debug symbols for gdb
backtraces to give more than a vague idea of the problem location.

It turns out that the problem is that svn-push.c is failing to
initialize the non-optional open_tmp_file ra_callback. This just happens
to work with ra_local, but breaks when using ra_dav.

(I’m about to commit a fix to svn-push.c)

Max.
