[php-maint] Bug#696626: (libapache2-mod-php5: infinite recursion in rfc1867_post_handler when trying to preview/commit a mediawiki edit)

[Nye Liu]

After installing the debug symbols, i get

#87243 0x00007fbe62b3623b in php_session_rfc1867_callback (event=0, event_data=0x7fffa99ebeb0, extra=0x7fffa99ebda0)

Probably a dup of bug #694473
