Bug 116307

I did "rm .kde/share/config/kdesktoprc" and then kdesktop did not crash again.
I have a backup of the config file though. 

Maybe its a good Idea to fix this anyhow because IMO many KDE upgraders will have a problem when they upgrade to 3.5 otherwise...

I played a bit with the old kdesktoprc:

This was my [Desktop Icons]-Section:
------------------------------------
[Desktop Icons]
Preview=imagethumbnail,cursorthumbnail,ldifvcardthumbnail,djvuthumbnail,exrthumbnail,htmlthumbnail,pothumbnail,gsthumbnail,fontthumbnail,svgthumbnail,picturethumbnail,audio/,textthumbnail,videothumbnail,webarchivethumbnail
ShowHidden=false
VertAlign=true
------------------------------------

Removing that strange "audio/" entry fixed the problem, but I do not know where this came from. I never edited the kdesktoprc file by myself with a text editor .

Maybe a check/filter for those entries while reading the file would be a good thing?

Me again ;)

Ok finally it seems that the "preview" of Sound-Files is broken. If I check the setting to preview sound files on the desktop ind the kdesktop-Settings, kdekstop crashes immediatly when moving the mouse over any icon, at least Folders and wav-Files.

So the audio/ entry seems not to be "weired" but normal.

Cheers

Can you paste the crash backtrace, please? I believe the crashes with audio files have been fixed.

Thank you, thought so.

The bug is in your gcc (libstdc++). Notify your distribution to fix it ASAP: a fix has been available for a while.
