Bug#734124: wesnoth: fails to exit is alsa is used by asterisk

[Tzafrir Cohen]

Package: wesnoth
Version: 1:1.10.3-3
Severity: minor

Dear Maintainer,

I noticed that on my system occasionally wesnoth hangs when attempting
to exit. The window is left frozen. Killing the process with SIGTERM
doesn't help.

After a while I noticed that the window is released (and the program
terminates) if I run the following:

  asterisk -rx 'module unload chan_alsa.so'

To reproduce:

# As root:
apt-get install asterisk wesnoth
# probably not required. Just in case:
asterisk -rx 'module load chan_alsa.so'

# As an X user:
wesnoth
# and try to quit it

Expected result: wesnoth exits.
Actual result: wesnoth hangs, as described above.

I also note that that I get no audio in this case. But I don't consider
this a bug of wesnoth.
