I've since updated from F16 to F18 (and all the kernel/driver updates that entails) on the same hardware, and it appears the problem no longer occurs for me.

Is this still an issue? Could you please verify that it is an issue with 0.3.0, and if the current disper bzr trunk solves it?

I used the python fix from Mike Cook in comment #14. It works fine now. I'm wondering if it's related to some python updates that I've received within the last couple of weeks.

Thanks, Mike, for getting to the cause of the problem! This might be a bug in X (especially if a protocol detail differs between i386 and x86_64), but at least we can workaround it.

Now, that's not a proper solution (should check the data length is long enough), but hopefully it helps identify the issue of why sz isn't getting set properly.
