Thread Safety is disabled (shown in phpinfo()), but i did never
enabled it on our servers, and we have lot... and i'm using apache2-
mpm-prefork... these default configurations ran never in trouble for
me, on high traffic sites too, but in this case it crashes on each
request. =(

Are you perhaps running a multithreaded Apache server with a
non-thread-safe PHP module?
Check "Thread Safety" in phpinfo() and whether you have
apache2-mpm-worker or apache2-mpm-prefork.

Its really strange, because i have several php53 installations without
any trouble with the same configuration, but only on one dev server it
crashes. if you cannot reproduce, its not a big deal that you can get
access to our dev server, there are not secrets and no data...

I can't reproduce this. Where in your apache.conf do you have that
line? As in which config blocks is it inside?

Segmentation fault if the following line is enabled in apache.conf:
php_admin_value open_basedir

Maybe i made something wrong or its not a bug in php, because i not
really understand the debug output, but i hope it helps =)
