Comment(by Quozl):

 Tested in Q3A29, symptom still occurs.

 Simplified Reproducer:
  * on build os108 insert a USB stick of at least 1Gb capacity, with no
 content of value,
  * wipe all partitions and create one of 1050000 sectors, with an ext2
 filesystem,
  {{{
 parted --script /dev/sdZ mklabel msdos
 parted --script /dev/sdZ mkpart primary ext2 0 1050000s
 mke2fs -q /dev/sdZ1
 }}}
  * insert into a laptop running Q3A29 and power up, hitting ESC to obtain
 ok,
  * obtain a directory listing and use to-file to create a file.

 Output:
 {{{
 ok dir u:\
 ext2-file-system
 [... lost+found listed ...]
 ok to-file u:\test cr
 Flushbuf error
 ok
 }}}
