Subject: [PATCH] [DOCBOOK] fix segfault in docproc.c

From: Henrik Kretzschmar <henne@...htwindheim.de>

Adds a missing exit, if the file that should be parsed couldn't be opened.
Without it crashes with a segfault, cause the filedescriptor is accessed even if the file could not be opened.
This error happens on 2.6.18-rc4-mm[12] when executing make xmldocs.
