Hello Fredrik
You used "-n" option  in the e2fsck command. So  the "WARNING:
Filesystem still has errors" tell all.
You SHOULD run e2fsck without the -n option BEFORE trying to mount it
and back up data or trying to resize it !
Otherwise..... you could well loose all the data !
Just my 2¢ .....
BTW : it is strange that all multiply allocated blocks are found to
belong only to one file. What was the system doing during the resize ?
What was the file system activity during that time ? And las t but not
least, you once told us that before running the resize, you ran the
fsck. Was it with -n option also ?  This may explain all the subsequent
events.
