My .xsession-errors file grows quickly and is currently over 150MB. It contains a lot of lines that seem more like info rather than errors such as "loading plugin ..." for many programs such as Kate an Deadbeef and seems to log every connection attempted by ktorrent.
Is this expected behaviour or a bug?
Some sample lines

There are a lot of errors logged which don't seem critical, but "exited normally" doesn't sound like an error.
