Hello, enlightenment:0.18.5 (from enlightenment overlay) crashes when entering Settings Panel -> Screen -> Screen settings. I have dual-head setup with xinerama support. Xorg-server is 1.15.0, nvidia-drivers are 304.121 (my card is not supported in newer branches). You can find output of 'emerge --info efl elementary enlightenment:0.17' my xorg.conf and .e-crashdump.txt in attachments below. I have the same problem with enlightenment-0.17.6 from portage, though it "just" hangs and produces no crashdump.

probably want to retest with the latest version ...
I'm staying with e16 right now, so can't test.
