... that has cropped up since I have TRIM'ed and noatime'ed and "none /tmp tmpfs size=10% 0 0"'ed my laptop SSDs.
Gnome-terminal segfaults upon starting. (Whilst running Gnome3/Gnome Shell) It is easily corrected by logging out and back in, and it doesn't seem to be correlated with anything else, but it sure enough does. Previous to making the above mentioned adjustments, the problem did not surface. However, given the nature of intermittent issues, that one cannot be carved in stone as completely true.
Alas ... It is an intermittent occurrence, though, and may not be related at all, but having two seperate laptops,with two separate SSDs (different brands) present with the same symptoms ... one has to wonder. <..
Methinks this one is going to be fun to chase down. <..
