Fileopenlog flag breaks cooking

I’ve been trying to get UE4 to cook content for linux, but it crashes each time I do. I copied the command out of the logs (below) and narrowed the problem down to one flag. “-fileopenlog”… If I remove this flag, I can cook content.

Is this a bug?

Here is the command I took from the logs

./UE4Editor MyProject2.uproject -run=Cook -MapIniSection=AllMaps -I18NPreset= -TargetPlatform=LinuxNoEditor -buildmachine -Unversioned -fileopenlog -abslog=“/home/user/Library/Logs/Unreal Engine/LocalBuildLogs/Cook.txt” -stdout -FORCELOGFLUSH -CrashForUAT -unattended -AllowStdOutLogVerbosity

Sample logs from failed attempt at cooking:

Version = 4.7.6
Os - Linux ( Kubuntu 14.10 )
