Description Nelson Jovel 2005-09-20 02:00:06 UTC

Version:           2.2 (using KDE 3.4.0 Level "b" , SUSE 9.3)
Compiler:          gcc version 3.3.5 20050117 (prerelease) (SUSE Linux)
OS:                Linux (i686) release 2.6.11.4-21.9-default

After deleting a folder through the konqueror window I was unable to start Juk.  The folder I deleted had been a folder referenced in the Juk folder list ( the list of folders in which to search for music).  When attempting to start Juk, I received a dialog box with the following error: The file or folder /home/joveln/Documents/test folder does not exist.  Closing that box presented me with the KDE Crash Handler box.  It read “The application Juk (juk) crashed and caused the signal 11 (SIGSEGV).  Juk stopped loading, and I was returned to the desktop.  Someone previously submitted a report similar to this.  They had reorganized their audiobook collection, moving folders around and deleting some files.  The status on that report is "Resolved", with the last comment being "not enough information to fix this error".


Here is what I did to work around the error.  I navigated to HOME/.kde/share/apps/juk  and renamed the cache file to cache-old.  I started Jukbox again.  It gave me an error message “folder does not exist” but this time the program loaded successfully.  I then removed the folder in question from the jukebox folder list.  I closed Juk.  I renamed cache-old to cache.  And finally I restarted Juk, it worked correctly and loaded all of my music.

Comment 2 Michael Pyne 2005-09-26 03:16:26 UTC

Confirmed, will try to fix before 3.5.

Comment 3 Michael Pyne 2005-09-26 03:32:56 UTC

SVN commit 464006 by mpyne:

Don't allow KDirLister to throw up its own error messages.  This seems to prevent JuK from
crashing during startup when adding its folder list to KDirLister when a folder has gone
away in the interim.

SVN commit 464008 by mpyne:

Backport potential crasher fix to KDE 3.4, involving KDirLister and calling openURL on
non-existant directories during JuK startup.

If this doesn't fix the bug please re-open.

Comment 6 Chani 2005-10-21 08:00:09 UTC

what version is this fixed in? I'm using juk 2.2.1 on kde 3.4.2 and I got the same problem (easy to fix when you know where the config files are, though).

Comment 7 Michael Pyne 2005-10-21 22:46:58 UTC

It might be in 3.4.3 if I backported in time.  If not you can either build Subversion kdemultimedia from branches/KDE/3.4 or use KDE 3.5 Beta 2 which has the fix, or wait for the 3.5 release.
