Comment 166 for bug 401823

the * ist just because there is also a file called .xsession-errors.old

if you switch this on/off in your session-properties, in case you want to view the log file, with this XID-collision flooding, it may happen, that the .old-file also get's quite big.

maybe the * is too much, but it's not harmfiul for other files. of course, your version is the exact way to do it. also the ' instead of " are better.
