 Leaving the UI on the program guide grid display causes the memory used by
 mythfronted to steadily increase until it crashes with
 QImage: out of memory, returning null image
 QImage: out of memory, returning null image

 mythfrontend logs don't seem to show anything happening.

 Using
 MythTV Version   : 21510
 MythTV Branch    : trunk
 Network Protocol : 48
 Library API      : 0.22.20090824-1
 QT Version       : 4.5.0
 Options compiled in:
  linux debug using_oss using_alsa using_backend using_dvb using_frontend
 using_hdhomerun using_hdpvr using_iptv using_ivtv using_joystick_menu
 using_lirc using_mheg using_opengl_video using_opengl_vsync using_qtwebkit
 using_v4l using_x11 using_xrandr using_bindings_perl using_bindings_python
 using_opengl using_vdpau using_ffmpeg_threads using_live using_mheg

 and the graphite theme.

 Machine is :
 Core2 Duo E7400  @ 2.80GHz
 4GB RAM
 GeForce 9400 GT

 It only seems to be an issue using OpenGL, "-O ThemePainter=qt" doesn't
 seem to show the same issue.

 Xorg process jumps up to ~65% while in this screen, mythfrontend is at
 35%.  Going up one level in the menu and they drop to 1% for Xorg and
 average in single figures for mythfrontend peaking at 14%.

 Memory usage stays high but stops increasing, going back into the guide
 grid starts it increasing again.

 What can I do to provide some more information?  This is very repeatable
 for me.
