Description of problem:

I recently upgraded my server from FC4 to F7.  One of my daily tasks is running
doxygen to build the nightly documentation for the project.  When I first
upgraded, doxygen was throwing a bunch of warnings every night due to deprecated
configuration parameters.  After updating the configuration doxygen now crashes
every time it's run!  Here's the stack trace:

Program received signal SIGSEGV, Segmentation fault.

Version-Release number of selected component (if applicable):

doxygen-1.5.2-1.fc7

How reproducible:

Appears to be completely reproducible with the current gnucash configuration
(which I've attached).  If you want I can explain how to reconfigure the sources
out of SVN such that you'll get the current doxygen config.

Steps to Reproduce:
1. run doxygen against the config
2. watch it die a flaming death
3. cry, because your script deleted the html output already and now you have no
docs.
  
Actual results:

SEGV.  See the backtrace above.

Expected results:

Nice, pretty documentation based on our sources.

Additional info:

See attached config file.
