Description Marcin Gryszkalis 2009-11-01 02:12:07 UTC 
Version:           1.68.0 (using KDE 4.3.2)
Compiler:          gcc 4.3.4 
OS:                Linux
Installed from:    Gentoo Packages

The problem came out when I installed num-utils package which provides its own normalize tool. K3B tries to check version numbers by calling something similar to "normalize --version" and parsing it's output. Unfortunately num-utils' normalize doesn't quit after printing version (it stays alive forever reading from stdin). K3B hangs there waiting for normalize to finish. 

I reported bug in gentoo bugzilla [1] about conflict (sound/normalize vs num-utils normalize) but I think it's still more general problem. I think K3B should use some kind of watchdog timer and kill offending tool if it doesn't behave as expected.
