I think this should have been documented by pulseaudio (I mean in case
they knew the problem)
because it would have saved a ***lot*** of time to people like you and
me. Not to mention that
chasing non-existent bugs is likely to leave you in an urgent need of a

I can't tell you what you're specific issue is (as I'm running fbsd),
but recently I spent months chasing a bug in my own app, which ended
up being a thread related bug in pulseaudio, so you might be right
there. I too had to disable window and button sounds. It appeared the
gdk lock wasn't handled properly in pulseaudio. This was solved by
upgrading the pa release.

I'm trying to debug a gtk app on Ubuntu Karmic that crashes from time
to time when I open a
dialog. Lately, I have found a precise sequence of UI actions that
always reproduces the bug
(I open a dialog, pick an option, click or enter ok, then re-open the
dialog.) But many other
sequences crash my app too. And I always get this error:
Assertion 'pthread_setspecific(t->key, userdata) == 0' failed at
function pa_tls_set(). Aborting.
So my app seems to crash because an error in pulseaudio, which is
strange. I made some google
searches and apparently, this problem exists with other apps
(Abiword, Flash support in Firefox,
Gimp, ...) Then, following a suggestion in a bug report, I opened
'sound-preferences' and disabled
'window and button sounds'. And then, no more crashes, ever.
I've already posted on this list about the problem and I don't want
to spam. But I've been re-
checking my sources many times since last month, unsuccessfully. Then
my app used to be very
stable a couple of months ago and I have checked all the last changes
I have made lately. So the
question is: could all this relate to an upgrade to Karmic or a newer
version of pulseaudio?
I know that gtk handles events from windows and buttons and so does
pulseaudio. Could it possibly
be a bug in pulseaudio on ubuntu (instead of in my app?) Does anyone
have an idea of what's going on?
Thanks in advance for any clue.
