As part of the big bug clear up for 16.04 LTS I am marking this bug as Wont Fix.
These types of crasher are better handled by errors.ubutnu.com which can
collate similar crash reports to help us identify persitent bugs rather than
one-off crashes.
Sorry we are not able to help with this specific
@willcooke:
- This *is* a persistent bug.
- errors.ubutnu.com does not exist
- this error is not ubuntu-specific. What happens in this case?
Reproduction instructions are quite clearly described on this ticket.

I had this bug on ArchLinux and Fedora with compiz 0.9.4 on the same PC.
Upgrading to compiz 0.9.5 (development release) fixed this issue, can
someone verify this is also the case on ubuntu?

Removing window matching rules in Window Decorations - Shadow Windows
resolved the crashes for me, too (now I'm using devilspie to unshadow
windows).
Window matching rules in other plugins (like Animations) work fine, so
the Window Decorations plugin seems to be the source of trouble.
I'm
I first noticed this problem when I started running Conky. However, it
had nothing to do with Conky itself, but rather with the rule I put in
ccsm (CompizConfig Settings Manager) to disable shadows on the Conky
window [i.e. Window Decorations - Shadow Windows = (any)
!(class=Conky)]. This

I'm including an attachment generated with compiz 0.9.4, though not on

so I won't have access to it for some time).

I forgot to say; the crashes are not only when alt-tabbing, but also
when opening menus, if I open File, then Edit, and go back and fourth a
couple of times, I get the same crash. Disabling regex matching fixes
BOTH crashes, so I've always considered them the same one.

The same issue ocurrs on Fedora 15, and ArchLinux with compiz 0.9.4, so this is
an upstream compiz bug.
On Arch, the issue ocurrs whenever a tooltip is displayed, or a menu is opened.
Disabling regex matching prevents these crashes.

I seem to be having this a lot more when I'm running conky. I'm not sure
if that's related.

same here.. compiz is unusable due to frequent crashing. After crashing,
dmesg says:

And the only thing that is saving face (with me) right now is this in a
terminal window:
$ while [ 1 ] ; do compiz --replace; done
It is crashing and restarting (per the loop) with no discernible
pattern.
