Description Luis Villa 2005-07-27 14:10:57 UTC 
I've now seen this twice in the past few days; I'm running basically HEAD
everything with accessibility turned on. The traces are slightly different, but
the top few frames seem to be the same, so I've filed them together.

Second trace- this one happened when I was launching an app that opened a
notification area icon.

Well - it's sending a message to the at-spi-registryd and blocking for the reply.
Why it's not replying (or dying) is up to at-spi-registryd.

Also - it's best to use 't a a bt' if there are other threads (looks like there
may well be in this case).

Finally - at-spi-registryd is prolly blocking on some AT it's trying to talk to
- what ATs do you have running ? what state are they in ?

Ah, OK. Bill? :)

Will do next time I see it. Have gotten out of the habit.

None; at least none that I've actively run/turned on- I had the accessibility
framework turned on for some QA testing, and left it on, but the QA stuff is not
running or nor has it even been run since my last reboot.

I don't see how the second trace can be at-spi-registryd's fault, but then again
I am not 100% sure what is happenning in the part of the trace above
Bonobo_Unknown_unref - why is the moniker code getting called?  ORB re-enterancy?

sure - the 2nd is just re-enterancy during an at-spi call out I guess. Why the
method is hanging, I have no idea. Need to see the other threads & other
processes it might be talking to to see what they're up to.

So, yesterday I discovered a way to reproduce this fairly repeatably:

* killall clock-applet
* reload? (yes)

and it would hang in the reload dialog. However, I rebuilt this morning to get
latest code and a full trace, and now I can't reproduce. Grr. So, I'll try again
later, but for now this is NEEDINFO, I guess?

Still can't duplicate. Closing.
