WTH is going on? Any ideas? I thought it might be my ati binary
graphics drivers, (although this was never a problem before), so I
put them in "wine TLS compatibility mode", or whatever, but no change.
Maybe something with my new 260-test4 kernel?
Running a simple test program which does getpwuid( getuid() ) works fine.
I do not buy, in the final analysis, that this is anything to do with nss
or nscd (which I don't even run, although running it doesn't fix anything)...
in fact I have a wierd suspicion that it really has to do with the server
socket thingy in /tmp/.wine-greg/...
creepy, and frustrating... but disturbingly, kind of fun :) As usual, it's
probably my fault, moronic and totally avoidable.
