Bug#612998: /usr/lib/nvidia/libGL.so.260.19.21: OpenGL-enabled Cairo + nVidia libGL cause Vim child processes to deadlock

Package: libgl1-nvidia-glx
Version: 260.19.21-1
Severity: important
File: /usr/lib/nvidia/libGL.so.260.19.21
I'm filing this against libgl1-nvidia-glx since using the libGL.so.1
from libgl1-mesa-glx doesn't exhibit the problem, but I'm open to the
concept that nVidia's library just happens to be exposing a weird bug
(in Cairo or Vim). As a reference, I've also included the version info
for Cairo and its dependencies in the reportbug template.
Since the recent OpenGL-enabled Cairo was uploaded (1.10.2-2), any time
Vim tries to fork a child process, the process gets deadlocked between
the fork() and the execvp().

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
An easy way to reproduce the problem is to run a Vim binary that's
linked against Gtk[0] (and therefore Cairo) and run a shell command from
inside it.
$ vim
:!ls
Instead of seeing the output of the working directory, the child process
hangs as described above. Running «ps afx» will show something like
13597 pts/6 Sl+ 0:00 \_ vim
13599 pts/6 S+ 0:00 \_ vim
when the child should be ls (and should have quickly exited). You'll
have to «kill -9» the child to get control back to the parent Vim
process since the child locks up before reseting all of its signal
handlers to default.
If there's any more information or help I can provide, just let me know.
[0]: Both the vim-gtk and vim-gnome packages will provide such a binary.
