After running syncthing on Mac OS OX, and setting it to point at a folder with a lot of files, syncthing now seems to be stuck with all repositories showing as unknown.

Attached is a screen shot of the GUI whilst it's starting up, and pasted below is the log showing the deadlock detected after a few minutes:

Same problem here (even the name "~/Projects" is the same) on Linux. Link to output. In my case the folder contains ~120k entries (98k files and some folders).

Yeah, sorry about that, the timeout was bad. Increased to 20 minutes, which should be enough, and I'm interested in the backtrace if it isn't. If I'm still wrong, it can be disabled with something like STDEADLOCKTIMEOUT=100000 syncthing.
