Here is a simple-minded fix that keeps Squeak from going off the deep when it attempts to report an error and the log debug stack to file preference has been set but the SqueakDebugLog.txt file cannot be opened.

I noticed this because my Squeak directory was not writable by me. There are many other uses of FileStream that fail ungracefully under such conditions (such as filing out), though not in a recursive loop like the above failure.  We should investigate these when we have added Exception support.
