Fix glibc crash: add log message on fopen failure

Browse Source 
glibc's fclose implementation does not do a NULL check and will crash on "fclose(NULL)". A bunch of Fedora users have been sending in traces for this issue. I've added a log on failure case, likely if the user does not have permission to write to the file.
