I think this was fixed for good with bug 805303, so it's a duplicate.
However, as both bugs already have tons of duplicates, I just close
this, instead of generating even more bug spam mail by duplicating.

I can reproduce this. Running metacity in gdb is a bit tricky as it
keeps locking up, but I was able to generate a core file, and then
produce a stack trace with full symbols from it. This was run with
--sync.
** Attachment added: full stack trace with --sync
I did a few obvious checks:
* unapplying all our patches doesn't help
* upstream git head doesn't have any code changes since 2.34.1
* upstream git head with -g -O0 still crashes
Right before it crashes, metacity logs
Log level 16: Native children wider or taller than 65535 pixels are
not
I don't know it it's related, but if I disable overlay scrollbar before running
vlc, then metacity doesn't crash
$ export LIBOVERLAY_SCROLLBAR=0
$ vlc
works fine.

And indeed we see in the stack trace:
#12 0x7fc81b7c18dd in _gdk_pixmap_new (drawable=0x134c5a0,
width=564, height=65535, depth=24)
even though the log message says that 65535 should still just barely
fit, it does seem like a bug.
No part of the stack trace goes through metacity here, it
ah, so vlc is making metacity crashes? Seems related to a fix I just
pushed for bug #805303 (linked to overlay-scrollbar)

I confirm that with LIBOVERLAY_SCROLLBAR=0 these don't happen. This is
most probably a dupe of bug 805303.

+ Disable overlay scrollbars before
In the beginning of vlc.out there is a line which says:
Blocked: call to putenv(LIBOVERLAY_SCROLLBAR=0)
That could be the problem. Anyone knows where this Blocked line comes
from?

Never mind, comment #62 from bug #805303 explains the reason for the
Blocked line.

It seems that you are still experiencing that bug (#805303), maybe it's
a good idea to reopen it?
Some other people also get it with the patched version, see comments 69, 71, 73.
And comment 62 suggests that this can happen because of calling putenv() in
multi-thread application.

Can someone recreate this whilst running metacity with the --sync
option? The stacktrace here isn't much use, as it's not where the actual
error occurred

this seems to still be an issue with latest package on Oneiric,
targeting to it so it can be fixed there.
