Klaus,
I've tracked this issue down. It was indeed due to byte ordering. The
version number was being read incorrectly. Attached is a patch for
the fix. It have been committed to git master. I'll ensure that it
gets into the 3.8.1 release as well.

Fixed FlashReader issues on BigEndian machines.
FlashReader was reading the version number information incorrectly on BE
machines. Fixed that.
