If I rip a CD to flac (I haven't tried other formats, e.g. ogg or mp3, wouldn't be surprised if those were affected too) k3b will stall with the progress bar around 96%.  It actually produces a full albums worth of listenable files (in particular the last track is ripped to a listenable flac file) but k3b does not complete the process or respond to "cancel", so I have to xkill the program.  So far k3b has done this for two CDs (and I have only attempted to rip two CDs with k3b).

Reproducible: Always

Steps to Reproduce:
I've only done this twice, but:

1) Put a CD in, open k3b and start ripping to flac.

2) When the tracks are successfully ripped to file k3b will be frozen.

Actual Results:  
k3b became unresponsive to normal user input and ceased to make progress in "completing" ripping the CD.

Expected Results:  
k3b would finish the "rip audio" dialogue and sitck me back at the main menu.
