Public bug reported: In Ubuntu 12.10, the UCSF Chimera molecular graphics program, http://www.cgl.ucsf.edu/chimera/, crashes when the SideView tool is brought up. This was not a problem with Ubuntu 12.04. I have reproduced the bug with Intel Integrated graphics, and have a bug report from a user that it happens with the AMD proprietary driver. So it is probably not the "new and improved" Intel driver (the usual suspect), but something more basic, like compiz/unity or whatever Ubuntu is using now.
To reproduce the bug, download and install UCSF Chimera from http://www.cgl.ucsf.edu/chimera/. Then, using the menus, use File / Fetch by ID ... to get the 1yti data set from the PDB (Protein DataBank), and then bring the SideView with Favorites / SideView. On my "Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02)" system, if the SideView is displayed before fetching the data, then it works. That suggests that it is a bug with sharing OpenGL data with a context that already has data in it. Here is the backtrace from gdb: Program terminated with signal 6, Aborted. #0 0xb7732424 in __kernel_vsyscall () (gdb) where 20 #0 0xb7732424 in __kernel_vsyscall () #1 0xb74611df in ??
