This is also occurring on one of my systems and was initially thought to be the "Xinerama pWin/pDst qt bug".
However, it occurs with xorg-server 1.9.4 and nouveau 0.0.16_git20101217-1 upon launching emacs. Process trace for Xorg attached. ** Attachment added: "strace for /usr/bin/Xorg" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/711422/+attachment/1856140/+files/xorg-trace.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. https://bugs.launchpad.net/bugs/711422 Title: Xorg assert failure: *** glibc detected *** X: double free or corruption (!prev): 0x089f5b20 - Unhandled dwarf expression opcode 0x9f _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
