First, note that you "hijacked" a different thread (Preserving Pan 
Session History...), probably by replying to it and changing the 
subject.  It still has the Message-ID of the previous message in the 
References header, however, so it's still part of the previous thread and 
will be displayed as such in many clients (including pan, when viewed as 
news on gmane as I do), regardless of the change in subject.  Hijacking 
threads isn't nice.  =:^(  Use the new-message functionality next time 
instead of hitting reply, and it should start a new thread. =:^)

As to your question, why don't you use a simpler Xref match of 

Xref: :.*:

AFAIK, that should do what you need I think (do colons need backslash 
escaped or not, I always have to test and see).  It /may/ be that pan is 
seeing those {} and trying to parse them as a test grouping (see the slrn 
scorefile doc) tho it shouldn't as they don't meet the criteria in the 
middle of a line like that.  But that could be why it's failing.  But 
your regex is simple enough I don't think it needs the {} anyway.
