Hey guys I try to use shortcuts and arrow keys with nautilus and I get this every time

MNU :�� receiver of doSemanticsAnalysis: is nil

in ASTCache at: aCompiledMethod

I would paste the full stack but it keeps throwing me MNUs when I try to do anything with the debugger. Seems like a pretty major bug , am I the only one experiencing this ?

I am on macos Yosemite using latest pharo 5 image and stable vm�� with

wget -O- get.pharo.org/50+vm | bash
