Comment 8 for bug 137514

As I've mentioned before, I noticed crashes often (though inconsistently)
when the mounts are used intensely, like copying movie files or lots of
directories, and when telling Amarok to scan the (100GB+) music collection.
There are crashes in other cases, but I didn't notice a pattern for those.

However, the crashes in the reproducible case go away if I mount manually
with "sshfs -f -s -o sshfs_sync -o no_readahead -o cache=no". It might be
useful as a workaround (I think most of those options can be given in
fstab). Someone with some time for debugging might try combinations of some
options to find out which one actually causes the crashes to go away, that
should point out the source.
