Xscreensaver user logout

[nomad]

Am running (updated) SL 6 on my main desktop box. Just wondering if anyone is running xscreensaver and is being logged out unexpectedly. Sometimes I could go for several days without being logged out. Sometimes after one day. Sometimes every few hours. I could not find any consistency. The screensaver is running 'GL Slideshow'. I have not tried other screensaver or the KDE screensaver. I found online one 'Unconfirmed' bug report about this. Never had this problem with xscreensaver in the 4x series.
