SSHfs crashes when trying to write files

[harrim4n]

I recently decided to connect my dockstar (arch arm) to my pogoplug (also arch arm) via sshfs. Everything works fine, the mount works without any problems, but as when I try to write into the folder the sshfs crashes. For example I can do 10 ls in a row, but when I try a touch everything goes down the drain, but not always. Sometimes I can rm and touch 5 files or so, but eventually it crahes.Here is the output when I touched /media/Data/test and then rm it and then touched it again, after which it crashed with the return value 139.
$this->bbcode_second_pass_code('', '
[harrim4n@DockStar ~]$ sudo sshfs root@plug:/media/Data /media/Data/ -o allow_other -o sshfs_sync -d

The output of the other shell in which I did the touch and rm is:
$this->bbcode_second_pass_code('', '
[harrim4n@DockStar ~]$ touch /media/Data/test
[harrim4n@DockStar ~]$ rm /media/Data/test
[harrim4n@DockStar ~]$ touch /media/Data/test
touch: closing ‘/media/Data/test’: Transport endpoint is not connected
')
Now, if I do an umount after the crash and execute the sshfs command again, everything's fine until the next crash.I really don't know what the problem is here and hope to get some help from any of you guys.
