Thanks for the report, I'm raising the severity to prevent it
migrating to testing.

Bug#1049983: panic: connection already exists

[Yuri D'Elia]

Package: syncthing
Version: 1.19.2~ds1-2
Severity: normal

With 1.19.2~ds1-2 syncthing panis immediately on the first connection
with the following error:

| goroutine 685 [select]:
| 
github.com/syncthing/syncthing/lib/fs.(*BasicFilesystem).watchLoop(0xc0002ec180,
 {0x12318d0, 0xc00066f7c0}, {0x1221680, 0x1}, {0xc00270ca00, 0x1, 0x1}, 
0xc0026a6480, 0xc0005f1080, ...)
| github.com/syncthing/syncthing/lib/fs/basicfs_watch.go:81 +0x13d

goroutine 836
| github.com/syncthing/syncthing/lib/fs/basicfs_watch.go:59 +0x453
| panic: connection already exists

Rolling back to 1.19.2~ds1-1+b5 and keeping everything else the same the
problem disappears...
