I don't think this has to do with truecrypt actually. In the first
message I said I thought this only happened with this file, but I was
wrong.
The latest file I tested it on (a 10 GB file) was not a truecrypt file
(it was a virtualbox virtual machine file). I also detected the same
problem with a 1.6 gb file which was a movie file (of course, after
removing its extension), however the latter only causes a momentary hang
(it actually loads the file to RAM for some reason, as i mentioned in
the previous message).

Thanks koro for all your info,
I haven't seen those log messages before, an interesting one. I'll keep
an eye out.
So it appears that this is only happening for TrueCrypt files with no
extension, yes? I believe what Daniel has said may on the right lines. I
will make my own 'large' true crypt file and see how things go.

Thanks to both for the interest.
Quicklook doesn't seem to be the issue (I can quicklook the file in
finder just find; it has no associated plugin so it just shows the
file name and date).
But maybe you're on the right track: It does seem like QS is trying
to load the file; I looked more carefully and when QS hangs doing
this, its memory usage (as shown in activity monitor) skyrockets. I
just killed it when it was using around 4.6 GB and still going up.
So I suppose it's trying to load the file to memory, and that's what
causes the hang.
I just did more testing, and it seems I was wrong: this also happens
with 10 gb files, as long as they have no extension.
I also tested a 1.6 GB file. It only hangs QS for a while (a while
during which its memory usage races up to 1.6 GB...) and then
continues normally (memory usage goes down after I continue).
What's going on here!
PS. (to Patrick) I just restarted QS and suddenly, a gazillon
messages showed up in the console (so many in such a short period
that it exceeded the 500 messages per second limit). I am sending
the logs attached, but I'm not sure this is related to my other problem.

Do you have QLStephen or another QuickLook plugin that might try
to create a preview for no-extension files? If you can QuickLook
the file in Finder, this isn't the issue.
If this is the issue, my guess is that the TrueCrypt volume
header looks like valid ASCII for the first however many bytes
`file` looks at to guess the encoding, while your example 10GB
file doesn't—so in the one case it's trying to interpret it all
as ASCII text, while in the other case it just gives up.
This is just the first thing that came to mind, it could easily
be something completely unrelated.

I have a very large file (20 GB) with no extension, which is
a Truecrypt container. When it shows up in the first pane of
the latest quicksilver version, I automatically get a beach

I can't find an explanation for this. I have tested and:
1) the problem stops if i change the file name to something
with an extension (like file.ext)
2) i tested a 10 GB file (which is the second largest file I
could find) after removing its extension, and I don't get
the same problem.
So there's something special about this file having no
extension AND there's something special about this
particular file or its size of 20GB (that does not happen
with 10GB)
Any ideas?
