Owner name: 䴀礀 娀攀渀
glibc detected free(): invalid next size

Aborted
The correct value for owner name is: "My Zen". Gnomad
uses this bindings, and as such can not be used (it
crashes just like the example program does). XNJB is
able to operate correctly on MacOS X, however (dual boot).
All other example programs operate without any
difficulties, and I am able to upload music & video
content to the device.

Update: Although I can succesfully upload content, the track
metadata arrives as a bunch of chinese characters as well.
Could there be a need for a byteswap here that is not
performed yet?

Hm. Since I have no big-endian thing to test on I assign
it to Richard whenever he may get the time to look at it...

Unfortunately the problem has gotten (a lot) worse in newer
versions, just tested 0.0.8 on PPC. The MTP session never
opens (although the LCD on the Zen Vision switches to
Docked) and return code 767 is emitted. I have confirmed
that the device is okay by trying on an x86 machine. The
owner string is reported correctly as "My Zen" on here as well.

This is a unicode handling bug somekindof, however
I am still unable to locate it without anything to
test on :-(

I hope this is fixed with the new iconv() code in
0.0.16, can you test?
Logged In: YES

The unicode conversion functions in unicode.c don't work on big endian
machines. If you use iconv instead it does work though.

We don't use the internal routines from unicode.c anymore,
we only use iconv() (even in unicode.c) so then it should
work now... Anyone tried on 0.0.16?
Logged In: YES
user_id=606537
Yep - works for me. As does 0.0.15 with iconv.

OK then I simply close this bug... I'm eagerly awaiting
the first XNJB using libmtp :-)
