I don't think this is duplicate of the bug #132130 - I'm running Interpid with all updates and I'm getting this error as well.

The problem appears only when using area selection and selecting the area from non-topleft side - ie. if I select the area from top-left everything works OK, if I select it from top-right to bottom-left it doesn't work. Looking at the debug line >

DEBUG: final pipeline: istximagesrc name=videosource display-name=:0.0 screen-num=0 startx=948 starty=568 endx=1022 endy=416 use-damage=false show-pointer=false ! video/x-raw-rgb,framerate=10/1 ! videorate ! ffmpegcolorspace ! videoscale method=1 ! video/x-raw-yuv,width=75,height=-151,framerate=10/1 ! theoraenc ! oggmux name=mux ! filesink location=/tmp/tmp1rnY5h

You can see that starty > endy, and that's why it fails.

You're right. Selecting an area from the top right or bottom left causes a crash when attempting to record. starty and endy values should be swapped.

Problem persists in 12.04. Selection from top left works, from top right doesn't. Tested on google earth with 3D capture on and mouse cursor capture off. Bug should be reopened.
