[exim] failed to unlink *-J in queue

Hello,

since upgrading to exim 4.82 and enabling cutthrough delivery for some
customers our paniclog shows now and then entries like this:

...
2014-09-04 03:23:11 1XPLlL-0001GW-6S failed to unlink
/var/spool/exim4/msglog/L/1XPLlL-0001GW-6S: No such file or directory
2014-09-04 10:51:30 1XPSkx-0000dv-Af failed to unlink
/var/spool/exim4/msglog/x/1XPSkx-0000dv-Af: No such file or directory
2014-09-04 13:53:17 1XPVbB-0000tE-9C failed to unlink
/var/spool/exim4/msglog/B/1XPVbB-0000tE-9C: No such file or directory
...

The files *-J stuck in the spool dir, *-H and *-D are removed.

The mainlog shows delivery of the mail:

The problem occurs only with cutthrough delivery and remains with exim
4.84.

Anyone else seeing this behaviour?
