6.2.1 .xsession-errors

[utu]

Upgrading IceWeasel from 3.5.6 to 3.5.10 has reduced most of the flash-video-induced .xsession errors here. I have codified a remaining six types of non-flash-related .xsession errors that I observed. Five of these now represent a minor, but puzzling continuing affliction. I have no reason to believe any of these non-flash-related .xsession-errors represent a performance problem, just an interesting puzzlement.
