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.

Comment 2 shattered 2007-02-24 21:53:44 UTC

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).

This bug should be fixed as of revision 683615.
