Would you like to view the file without these lines?

grep -v "unwanted_word" file | grep XXXXXXXX

-v reverses, so it finds everything BUT "unwanted_word"
The part to the left of the pipe | should do the trick. To the right of 
the pipe allows you to look FOR certain things in addition.

If you want to watch the file live, you can use tail -f file | grep -v 
"unwanted_word"

I guess you can also use the above to list the lines, then > it to a 
file name.  grep -v "unwanted_word" file > xsession_custom  will give 
you a new file without the annoying lines.

I can't tell you about bugs or how to fix the issue. Just a workaround. 
You can use regex with grep also.


Good luck.
