subversion / dav_svn_module : Fatal error 'Recurse on a private mutex.'

I have a strange situation on our internal svn server. Since a few days
and some upgrades, if I try to access a new created repository via
apache, I get a blank page and this error in the apache error log:

==> /var/log/httpd/httpd-error.log <==
Fatal error 'Recurse on a private mutex.' at line 986 in file /usr/src/lib/libpthread/thread/thr_mutex.c (errno = 86)
[Tue May 12 11:56:02 2009] [notice] child pid 64353 exit signal Abort trap (6)

The only difference between both repositories is the db/format file:

diff -r repos/websites/testing/db/format repos/websites/testing2/db/format
< 4
> 3

If format is "3" (subversion "pre-1.6"), everything works fine, but if
the format is "4" the DAV/SVN part crashes (while everything remains
fine via svn client / svnserve).

I guess I should recompile something (apache?), or change a
configuration somewhere, but I'm still looking where.  Maybe you will
have an idea?  I'd still like to be able to use SVN/DAV with the new svn
1.6.x features... 

Thanks & regards,
