Hello,
This has been fixed (or workaround - gsteamer developers are looking into
it, look into the gnome bug) in trunk subtitleeditor. Meanwhile, the patch
is attached to this comment. Change directory to the root directory of
subtitleeditor source and apply with
patch -p0 /path/to/fix-playbin.patch
Hope it helps someone!

Hi,
just as an update: upstream thinks that it's a Debian specific bug.
Could you please have a look at it:

I did get interesting output from valgrind though. The numbers below,
when
related to your earlier point about it seeming to be 64 bit specific,
seem
suspiciously like something is mixing 32 and 64 bit. There's a read of
size 8 4
bytes before the end of a block. It could be another bug though.
This all happens before gstreamer gets used, so seems either like a bug
in
glib's option parsing code (unlikely), or, since these are prebuilt
binaries,
someone mixing ABIs (more likely).
There's an invalid write later in /usr/lib/libgstreamermm-0.10.so.2.0.1,
which
would quite likely panic the libc malloc checks. This is fairly likely
to be
the same bug (writing 8 bytes where maybe allocated memory was smaller,
assuming 4 byte values). Can't tell for certain offhand though.
So I'd say not gst. Probably whoever compiled one of the libs or
subtitleeditor itself mixed up ABIs/archs. Probably subtitleeditor
itself, or
there'd be several more programs showing the same symptoms (are there ?
:))
Anyway, that's all guesswork based on the valgrind reports and the
offsets/sizes here. It seems likely, but I can't be 100% sure. That's
something
that distro people will know better how to check.
Please feel free to link to this comment to your distro's bugtracker. I'm
tempted to close as NOTGNOME, but I'll wait to see what those people say
before
doing so.
Thanks
