same again for me  on ftp://ftp.mirror.ac.uk/sites/ftp.suse.com/pub/ 

Package problem. 

Problem seems to exist for different people with different versions of SuSE 
distribution and different package sources.  
 
Konqueror also crashes when opening  a local directory in filemanagement 
mode, but not if invoked simply with "konqueror" from a terminal, but if started 
with the default icons in kicker.... 

So many crashes and no posted backtraces. Don't reopen without adding them!

I've found that this crash only occurs if I enable previews in konqueror. But also 
with previews enabled I can start konqueror without a crash from the command 
line, but not with kicker icons or with <Alt>-F2 

Yeah, it has something to do with sound previews, but not clear what.

just an idea, does it help to do 
 
export KDE_MALLOC=0 
konqueror ftp://ftp.kde.org  
 
? can you try to find out which plugin gets loaded (with strace) ?

  If this is really widespread and sound previews are really the cause, then 
we need to get this resolve asap (before 3.1.1) or disable sound previews in 
the branch.

I can confirm that this bug is related to the "View->Preview->Sound Files" menu selection.  I 
thought it was related to the file:// and fish:// protocol implementations ("Configure 
Konqueror...->Previews"), but after reading some of the comments here, I re-enabled them and 
switched off sound file previews.  Konqueror now shows file previews without locking up.  
Please note that if  "View->Preview->Sound Files" is enabled, there do not have to be any 
sound files in the directory - Konqueror will crash anyway. 

Linking to 47373 to have all the info in one place.. Sorry for the noise..
