Daniel, i'm still getting segfaults when exiting the watch recording screen
# mythfrontend --version
Library API version: 0.19.20060121-2
Source code version: 8722
Options compiled in:
linux debug using_xvmcw using_v4l using_oss using_alsa using_arts
using_ivtv using_dbox2 using_lirc using_joystick_menu using_dvb
using_dvb_eit using_x11 using_xv using_xrandr using_xvmc using_xvmc_vld
See attached backtrace.
Greping for "previewThreadDone took" in the frontend log gives me:
2006-01-25 21:42:14.936 Preview: previewThreadDone took 7ms
2006-01-25 21:42:14.943 Preview: previewThreadDone took 6ms
That's also the last thing in the log before the segfault.
