"org.ayatana.bamf.view" doesn't exist: compiz/unity reliably crashes while loading Evince from Thunderbird

Paul: we'on ubuntu4 atm, but nontheless can you specify the version of bamf and unity since it should be what creates the issue.

David: I'm not sure of the version of bamf/nux I had at the time, I currently have:

  bamf=0.2.64-0ubuntu1 unity=3.2.2-0ubuntu2

and with those versions compiz is no longer _crashing_... but 9 out of 10 times I don't see any output from Evince either (a white window pops up for <1 second and then vanishes):

  $ xwininfo -root -tree
     ...
     0x4000001 "Document Viewer": ("evince" "Evince") 10x10+10+10 +10+10
        1 child:
        0x4000002 (has no name): () 1x1+-1+-1 +9+9

vs. a normal "good" instance which looks like:

     0x4a001d5 "Document Viewer": ("evince" "Evince") 114x37+1271+105 +1271+105
        1 child:
        0x4a001d6 (has no name): () 1x1+-1+-1 +1270+104

If I grab the output (compiz --replace) then I see:

  ** (<unknown>:20289): WARNING **: Unable to fetch children: Method "Children" with signature "" on interface "org.ayatana.bamf.view" doesn't exist

after Ctrl-C-ing the non-visible Evince instance (but not on startup).

Adding a bamf task, to make sure this keeps being tracked as a potential issue and not get expired automatically.

I can't reproduce this from trying it now. I can't prove it's been fixed either. Will reopen if I have it again (there has been *alot* of churn in the last three months).
