Hello,

Since recently, Berlin sporadically fails during offloading with a
message such as...

Backtrace:
          10 (apply-smob/1 #<catch-closure 7fa16031f1e0>)
In ice-9/boot-9.scm:

Throw to key `match-error' with args `("match" "no matching pattern" #<eof>)'.

This seems to happen randomly, at different times and different machines.
