Files renamed only on the cloud

Some of my files (mp3 files actually), got renamed on the web interface, (.mp3 to something line .mp3.H12345).
I'm using the ubuntu one music android app, and those files where not syncing, maybe it's the music app that renamed them?

Anyway, the files have the correct name in my folder.

In the syncdaemon.log file I there are a lot of lines like this:

2011-06-28 23:18:44,000 - ubuntuone.SyncDaemon.local_rescan - INFO - generating Unlink from trash: share_id='' parent_id='b09c2bd7-2df9-427b-aea7-2c47502cd1b5' node_id='a35a4dbb-6ead-4eea-8bf6-87c25c381be5' path='/home/cascara/Ubuntu One/Musica/Red_Hot_Chili_Peppers/Stadium_Arcadium/03_-_Charlie.mp3.QQREN001REN'

and later a lot of these:
2011-06-28 23:18:44,023 - ubuntuone.SyncDaemon.local_rescan - INFO - processing move limbo
2011-06-28 23:18:44,024 - ubuntuone.SyncDaemon.local_rescan - INFO - removing from move limbo: share_id='' node_id=marker:bbc31683-91d0-4018-9a1d-7fb0ad70eaca old_parent_id='b09c2bd7-2df9-427b-aea7-2c47502cd1b5' new_parent_id='b09c2bd7-2df9-427b-aea7-2c47502cd1b5' new_name='03_-_Charlie.mp3' path_from='/home/cascara/Ubuntu One/Musica/Red_Hot_Chili_Peppers/Stadium_Arcadium/03_-_Charlie.mp3.C15310' path_to='/home/cascara/Ubuntu One/Musica/Red_Hot_Chili_Peppers/Stadium_Arcadium/03_-_Charlie.mp3'

In fact is That 03_-_Charlie.mp3.C15310 the file that is displayed in the web interface.
