Re: [Banshee-List] MTP sync adds invalid files, no album art

[IBBoard <ibboard gmail com>]

I've finally found the problem with the invalid files - an update in libmtp!

There was a commit [1] in March 2011 that adds "Folder" at the top of 
the libmtp.h enum. This obviously screws up the mapping that Banshee 
uses, so MP3 files in Banshee's enum were treated as WAV files by 
libmtp's enum, so my Creative Zen treated them as WAV files and failed 
to load them.

The album art issue appears to be caused by the check only checking for 
JPEG support, but the Creative Zen X-Fi support JFIF (which mtp-detect 
reports as JPEG support). If I add it "or JFIF" to the loop over file 
format support then I also get album art.

I'll write up a bug report and some patches this weekend, but if anyone 
else is having problems with MTP devices and invalid files or no album 
art then that could be the issue!
