How to recover a crashed game in Vulture's

I was playing SLASH'em with the Vulture's GUI, on Mac OSX. The applicatiion crashed, and now when I try to start, I get a popup telling me that I have a game already with that name, and asking if I want to destroy it. Selecting "no" quits Vulture's. Does this mean that the crashed game is recoverable, and if so, how do I go about doing so?

I've had a similar situation with normal nethack where there was a file left suggesting a game was in progress, but not enough to actually continue.

I had to manually delete the file to allow a new game to start. (I think it was a file with my username, but I don't recall for sure.)
