XBMC fails assert in pulseéstream.c on startup

Occassionally, when I start XBMC, the window comes up briefly, but it immediately exits out. Once the problem starts, I can`t make it stop, and the only way around it that I`ve found so far is rebooting. Running it from the command-line i`ve learned that it looks to have something to do with sound:

$ xbmc
The XBMC_HOME environment variable is not set.
StdString: Assertion Failed on line 916
StdString: Assertion Failed on line 917

and here`s my sound hardware:
$ lspci | grep -i audio

Anybody know what this is about or how to fix it

Thanks.

Try a newer build, if it still happens, check the sticky about posting problems in a useful manner for instructions on creating a stack trace.

I`m running babylon (9.04.1) and I don`t think anything later than that has been released. Would you like me to try from svn?

Edit: Nevermind, found there are svn build ppas. I`ve upgraded 9.04.3, we`ll see how that goes.

Just a note. This is always preceded by an unclean shutdown of xbmc. So it's leaving something around and not expecting this at xbmc startup.
