Just to make this clear before starting this is a Sid issue (as far as I can tell) not a Wine issue.
Anyway, to the point. Networking is broken on Debian Sid and has been for at least a week. I can't find out what has changed in Sid for it to stop working but basically anyone running Wine on Sid wont be able to use any form of network access. Firefox wont work, games wont be able to access servers or anything else, Gecko wont work, etc. This is using GIT, not the distros own packages.
I tried using the x86_64 package for Ubuntu 7.04 (because no x86_64 package exists for Debian) and Wine acted exactly the same way with a clean .wine so it's not related to any build time issues. I reset to 0.9.34 in GIT and built that to make sure it wasn't anything that has changed in Wine itself and the issue continued, so it's not something that's changed in Wine. Although using an earlier version of Wine gives a "Winehq.com could not be found, please check the address and try again". Current Wine (or rather Gecko) doesn't bother giving you an error message.
Could this be the work of the removal of an unspoken Wine dependency or something more sinister? All native apps still work perfectly which is what makes this such a hard thing to track down.
I just thought I'd throw this out there in-case any of you are using Sid and wondering what the the hell happened to Wine. Log attached for completeness.
