Title:
  gnome-terminal writes to /tmp on every line of output

Status in Gnome Virtual Terminal Emulator:
  Confirmed
Status in vte package in Ubuntu:
  Triaged

Bug description:
  STR:

  1. Start xterm
  2. Run "python -mpyinotify /tmp"
  3. Start gnome-terminal.
  4. Run some command like ls

  Actual Results:

  Observe a ton of IN_MODIFY lines such as
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vteD7DX2V path=/tmp pathname=/tmp/vteD7DX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vte1XDX2V path=/tmp pathname=/tmp/vte1XDX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vte72DX2V path=/tmp pathname=/tmp/vte72DX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vteD7DX2V path=/tmp pathname=/tmp/vteD7DX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vte1XDX2V path=/tmp pathname=/tmp/vte1XDX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vteD7DX2V path=/tmp pathname=/tmp/vteD7DX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vte1XDX2V path=/tmp pathname=/tmp/vte1XDX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vte72DX2V path=/tmp pathname=/tmp/vte72DX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vteD7DX2V path=/tmp pathname=/tmp/vteD7DX2V wd=1 >
  <Event dir=False mask=0x2 maskname=IN_MODIFY name=vte1XDX2V path=/tmp pathname=/tmp/vte1XDX2V wd=1 >

  Or, when idle -
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteGFOF2V path=/tmp pathname=/tmp/vteGFOF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteI7NF2V path=/tmp pathname=/tmp/vteI7NF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteVCOF2V path=/tmp pathname=/tmp/vteVCOF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteGFOF2V path=/tmp pathname=/tmp/vteGFOF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteI7NF2V path=/tmp pathname=/tmp/vteI7NF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteVCOF2V path=/tmp pathname=/tmp/vteVCOF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteGFOF2V path=/tmp pathname=/tmp/vteGFOF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteI7NF2V path=/tmp pathname=/tmp/vteI7NF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteVCOF2V path=/tmp pathname=/tmp/vteVCOF2V wd=1 >
  <Event dir=False mask=0x1 maskname=IN_ACCESS name=vteGFOF2V path=/tmp pathname=/tmp/vteGFOF2V wd=1 >

  This looks like vte code storing something. According to this question - http://ubuntuforums.org/showthread.php?t=1830432,
  "Sometimes vte creates temporary files which contains a copy of the whole scrollback buffer, [...]".

  Expected results:
  Nothing is being written to this dir at this rate by gnome-terminal.
