It has nothing todo with ADS as I used a tool to scan the entire portal 2 directory and got no results. However I had recently transfered my entire wine program directory to a NTFS partition where my windows programs files were stored ( reduce space considering I installed alot of games twice). The result was 2 different steam directories one with a working portal 2 and one without. I over wrote the broke portal 2 with the working one through windows. When I got back on Ubuntu and started Portal 2 I got a Virtual Call error rather than just crashing. The problem may be with ntfs but wine is obviously not copying a file correctly and the linux kernel can not transfer from the ntfs to the ext4 correctly.
Thank you for this. I suspected that the problem being lack of support for ADS was too simple too be true, but it needed ruling out. I still wonder about the possiblity of transient forks during authentication (very unlikely) and about Steam itself (less unlikely, but still unlikely); at least I get to shut up about it.
I think given your other evidence, it's clear that the limiting bug is with Wine right now. Is there an obvious difference between the working copy and the non-working copy?
