I get the same segfault as soon as I click on the TV icon

FYI:
grandr was written by <email address hidden>
It is under git version control here:
http://gitweb.freedesktop.org/?p=xorg/app/grandr.git

debian has this same bug here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=445310

The original poster over there claims to fix this bug by a dirty hack.
I did not try it out, because I found that the xrandr cli does everything I need.

[Brian Pitts (bpitts)]

Same bug; Inspiron 1420N.

[Václav Šmilauer (eudoxos)]

This fixes the crash as reported. I am not sure if the functionality is not affected, though.

There are still crashes if I click on rotation of external monitor. And, above all, it doesn't do anything really...

[Michael R. Head (burner)]

Got this crash with the latest hardy on a Thinkpad T30 with Radeon Mobility 7500 chip.

Can confirm this bug. grandr is currently unusable, selecting a display device results in a segfault:
