Hello,
Before looking up with what application a message error appears, it's 
good to consult the web starting from _the error message_ as for sure,
one error in a file somewhere can lead to the same error message in 
diverse circomstances. That's how the application with which the error 
comes can be totally independant of the cause of the message.
One other thing that can be looked up in diverse circomstances is the
/var/log/messages content (with the 'less' command or with the 'tail' 
command) or the very last log you'll find in your /var/log folder.
Best greetings, Joyce Markoll.
