Hi Guilherme,
Thanks for flagging this intel_miptree_release() crash still happens
with 8.0.1 mesa, since we'd understood that version fixed these issues.
However, apport appears to have gone to lunch and not collected a
backtrace or log files, etc. Perhaps since it believes this is a dupe
it didn't try? Anyway, we may need to have you gather these files
manually.
See if you can reproduce the crash while running unity in gdb. (Try
maximize/minimize windows a bunch, perhaps with some other graphical
things running in the background, and maybe switch desktops back and
forth.) Then when it crashes collect a full backtrace. Also attach
your /var/log/Xorg.0.log, `sudo dmesg`, and your ~/.xsession-errors.
Note that this latter file can sometimes include passwords or other
private details so you may want to edit it down; we really only need the
lines immediately leading up to the crash, to understand what was going
on.
