Apparently, Trolltech made some incompatible change to QTable’s code, and by “virtue” of this change, in-line retagging doesn’t work for me any more. I’ll endeavor to have this fixed soon, but I’ll be out to the US for about a week and a half at the end of March, so I suppose it’ll be a while. Hang in there…
Update: The problem appears to have vanished. So, I assume it was a temporarily broken Debian package. Or a fluke in the transjector matrix. Or whatever. :)
