Yeah. Since logfiles and saved games (just like modules) are merely renamed ZIP archives, I tried unzipping the file and got:
Archive: pave v bb invin v1.7 17.vlog
error [pave v bb invin v1.7 17.vlog]: missing 11973 bytes in zipfile
(attempting to process anyway)
error [pave v bb invin v1.7 17.vlog]: attempt to seek before beginning of zipfile
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)
(attempting to re-compensate)
inflating: savedGame bad CRC 58a02c3e (should be 4ccaa095)
file #2: bad zipfile offset (lseek): 311296
file #3: bad zipfile offset (EOF): 315885
