Firefox hangs when quitting

[Rached B]

Binary package hint: pulseaudio

When quitting firefox (with File -> Quit) sometimes firefox hangs. I'm attaching a stacktrace.

Not sure if the bug is invalid because of the use of flashplugin-nonfree, or if the bug is really in pulseaudio or libflashsupport or even firefox ...

* firefox 3.0~b4+nobinonly-0ubuntu1
* pulseaudio 0.9.9-1ubuntu2
* flashplugin-nonfree 9.0.115.0ubuntu4
* libflashsupport 1.9-0ubuntu1

I'm also getting this, usually when closing a tab in firefox which contains flash content. Backtrace looks identical. Using up-to-date Hardy beta (pulseaudio 0.9.9-1ubuntu2).

I have a nearly identical issue with a different application: ioUrbanTerror.x86_64. Periodically, the game will stop playing sound and when you look in the console it scrolls the message "Dropping sound" hundreds of times per second. When I try to /quit the game, it hangs and I have to drop over to a virtual console and kill the process by hand.

This is not the only problem I've had with pulse...

I'm not having this in Firefox (yet). Around noon today I exited Civilization: CTP. It's past 10PM now, and it's not actually finished "ending". I run it in a window because upon exiting various programs, the program hangs, and it still appears in the nice, new "Sound Preferences" application. Firefox hasn't been the problem even once.

My gut tells me it's trying to 'unhook' somehow and can't. These are all programs that are well-known, several of them are very old (like CivCTP). This suggests to me that a new way of handling sound to get it to work better has a little bug that was unintended.

My experience with PA has been pretty good, with one execption; I'm still pretty happy and know why it's so important to do. I saw the release of everything from Alsa to ESD, to-and-from various OSS drivers. I even have a quote, circa 1978 for it: "Every engine, literal or figurative, smokes on startup." That's the case here, too.

I'm on an AMD64x2, 1G, running Ubuntu Karmic, ALL from repos- no tarballs to complicate things.

It seems to be PA-related. Since my last post, I've seen all kinds of programs hang-on-exit, including FlightGear and others. Something's not getting released, but I'm no expert.

I'm highly available; if someone wants me to help, I'm almost always free, AND inclined to help.

Not PA but alsa-lib/alsa-plugins

Does this bug still occur? Which Ubuntu/ Flash version do you use?
