File from client causing hobbitd_client to crash

[Potter_Thomas at emc.com]

I am running Xymon 4.2.3, and a file I am trying to grab from a
monitored host seems to be causing hobbitd_client to crash. The file is
a textfile generated by an internal proprietary application. 

Here's a backtrace from the core:

Here is the file causing the trouble, /var/log/foo/proprietary.logfile
Due to corporate security concerns, I have changed all the digits to 9
and the alphas to X|x, as well as changing its name....

----End of file -----
There is one blank line at the end of that file. 
It's a version status file generated by the app from a cron job.

Relevant bit of ../server/etc/client-local.cfg:
--snip--
#Director version - requested by Ed/Gopi 12/2/09
[LSCA5235]
log:/var/log/foo/proprietary.logfile:10240

Relevant bit of ../server/etc/hobbit-clients.cfg:

--snip--
# Directors where we are monitoring versions

LOG /var/log/foo/proprietary.logfile
