Segfault in ws-daemon

[meysholdt]

Spottet twice in prod (here and here) after today's deployment:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x1c21260]

goroutine 1 [running]:
github.com/gitpod-io/gitpod/ws-daemon/pkg/dispatch.(*Dispatch).Close(0xc0002d8310, 0x0, 0x0)
	github.com/gitpod-io/gitpod/ws-daemon/pkg/dispatch/dispatch.go:152 +0x100

The call stack looks like the one from #5229
Container-version of ws-daemon: commit-2e90d32ba9ece42b8f56d1bb298c3ba53b4d2f99.

Line numbers are not matching anything sensible in this commit. To me it looks like the log is from a state before that the commit fixed.

Closing. Fixed in #5229
