Unfortunately I cannot. The bug appears to occur randomly and is truly insidious to track down.

All my attempts to reproduce have failed, but I still see the bug all the time. For example, just now I changed the title of a song. When I opened it up again in the metadata editor, it had exactly 30 characters (though the title on the playlist did not yet reflect this). Rechanging the name of the song and repeating my actions could not reproduce the bug.

Please tell me how to check if needed (see below for why it might not be needed).

see above; it seems to happen after making a change to metadata, but otherwise I just stumble across songs which have corrupt (truncated) metadata

I'm not using / don't use external software. Doesn't tag-encoding not being used anymore in 1.4.4 imply this is a problem with Amarok's database and/or metadata-editor code?

I've provided as much as I know in my previous email: namely that:
- This effects at least the artist + title + album fields
- This effect may occur after changing metadata with Amarok's metadata editor, but if it does the changes are not immediately apparent; e.g. they won't be reflected in the context browser or playlist. This might also occur to songs that I've never editted data for, but I'm not sure.
- Sometimes this will occur to an entire album (all songs will have their album data truncated to 30 characters; I can't remember if I was using the right-click-on-album change-album-metadata functionality at the time)

I've been trying to track this bug down for awhile. I even did periodic backups of my database for just the purpose of tracking all 30-character metadata fields. I haven't found any hint as to what might be causing this. (Albeit I have not looked at the code.)

Sincerely,
Mats
