Just to say I've got similar messages on a usb install. I'm running Chromium from the command line and getting 6 messages like below (XXXXX = random letters and numbers)
"ERROR:base/shared_memory_posicx.cc(192) Creating shared memory in /dev/shm/org.chomium.XXXXX failed: No such file or directory"
Chromium opens fine and appears to show that it is loading pages (the info message at the bottom left corner Loading
www.google.com.....) but I always get a blank page.

Just to add additional information. I just tried and booted tinycore_2.9.r2.iso (which I installed onto my USB drive) and then installed chromium and everything was ok, google showed and other pages worked. So it seems it's a problem with the USB installed version. I installed using the usbinstall button on the control panel.
Cheers
