That's a problem we had ever since TSVN was started. Because if you
have both TSVN and TCVS installed, then TSVN won't have enough overlay
slots available.
And it hasn't crashed because of that.

An easy solution to this problem: send me an invitation to the live
messenger beta, so I can install and it and reproduce the crash
myself. Then I can fix it.
Otherwise, you'll have to live with the crash until it gets out of
beta and I can use it too.
