Thanks for your reply. The behaviour is the same with a wine-git checked out and compiled today on Ubuntu 9.10: fixme:netapi32:NetUserAdd ((null), 1, 0x2f6c270, 0x2f6c268) stub! fixme:advapi:LookupAccountNameW L"" L"hela\\postgres" (nil) 0x2f6be84 0x1d05630 0x2f6bd6c 0x2f6be8c - stub I suspect the application to rely on PostgreSQL, so it is propably not related to wine but to a missing PostgreSQL.
