Description Daniel Roberge 2006-09-19 09:42:49 UTC
Version:            (using KDE KDE 3.5.4)
Installed from:    Debian testing/unstable Packages
OS:                Linux

In one of my collection directories I had, due to a software error, an empty file with a .flac extension. If I add this directory to JuK it tries to read the tag from the empty file and immediately crashes, without an error message, even on the console.

Still happens in KDE 3.5.6.
Comment 3 Geoff Oakham 2007-05-08 06:15:25 UTC
I found the a similar problem, except my flac file has a invalid header (apparently).  Here's what it shows on the console:

kio (KIOConnection): ERROR: Header read failed, errno=104
kio (KIOConnection): ERROR: Header has invalid size (-1)
KCrash: Application 'juk' crashing...
DCOP aborting (delayed) call from 'anonymous-10104' to 'juk'

I'm not attaching the file because it's 45M (and it's copyrighted).
