After a dist-upgrade, streamtuner now dies when reloading
shoutcast streams.

Libraries upgraded by latest dist-upgrade (which streamtuner depends
on):

libatk
libglib2

How it dies:

test@atlas:~$ streamtuner &
[4] 15679
test@atlas:~$ free(): invalid pointer 0x8257ec8!

[4]+  Segmentation fault      streamtuner
test@atlas:~$ streamtuner &
[4] 15683
test@atlas:~$ free(): invalid pointer 0x8257ec8!

[4]+  Segmentation fault      streamtuner
test@atlas:~$

Hm, I can't reproduce this on 0.99-2. There's a newer version,
0.99.99-2, in unstable, could you try reproducing it on the newer
version? But before you do that, could you run "ldd `which streamtuner`
| grep /usr/local" and if there is any output, send it to me?

 From http://bugs.debian.org/287121:

Streamtuner 0.99 segfaults with the cache file included in the attached
tarball. Trying the same cache file with Streamtuner 0.99.99 results in
streamtuner hanging on startup and using 100% CPU until it is killed. An
strace of streamtuner 0.99 was done, and it always seems to die at the
same point:

read(6, "\";\n\t\t\t\t\t\"http://www.weareasian.c"..., 4000) = 4000
brk(0)                                  = 0x824c000
brk(0x826d000)                          = 0x826d000
read(6, "\t\tarray {\n\t\t\t\t\t}\n\t\t\t\t}\n\t\t\t}\n\t\t\ts"...,
4000) = 4000

Not reproducible here. Please provide a backtrace of the 0.99.99
freeze (run inside gdb, hit ^C when it freezes, and type "thread apply
all bt").

reassign 287121 libc6-i686
thanks

Turns out that, at least in streamtuner 0.99.99, this is a bug with
libc6-i686, and is 100% reproducible with it installed, but not without,
and reproducible only without setting the environment variable
MALLOC_CHECK_=2 and without LD_LIBRARY_PATH=/usr/lib/debug if libc6-dbg
is installed. Talk about weird.

Steps to reproduce, for the libc6 maintainer:
1. apt-get install streamtuner
2. mkdir ~/.streamtuner
3. un-bzip2 the attached cache file, and move it into ~/.streamtuner.
4. run streamtuner. it should hang at startup while on the splash screen.

Rebuilding streamtuner with CFLAGS="-ggdb -O0" and running "gdb
streamtuner", then running it, then Ctrl-C when it freezes, gives the
following (useless) backtrace:

Whoops, forgot to attach the cache file. here it is.
