Title:
  libmagick hangs when called from RMagick with Passenger 3

Status in “imagemagick” package in Ubuntu:
  New

Bug description:
  ruby processes using libmagick via the RMagick gem hang when running
  under Passenger 3.0.11. The requests never return.

  Installing debug libraries and looking at one of the stuck processes
  with gdb gives this:

  #0  futex_wait (val=0, addr=0x3858984)
      at ../../../src/libgomp/config/linux/x86/futex.h:44
  #1  do_wait (val=0, addr=0x3858984) at ../../../src/libgomp/config/linux/wait.h:58

  #5  SetImageBackgroundColor (image=0x1d27600) at magick/image.c:2792
  #6  0x00007f876879749e in Image_initialize ()
     from /usr/lib/ruby/gems/1.8/gems/rmagick-2.13.1/lib/RMagick2.so

  The problem does not occur when using the Ubuntu Passenger package,
  only with more recent versions of Passenger.
