Bug 116566

Version:           1.3.6 (using KDE 3.4.3, PLD Linux Distribution)
Compiler:          gcc version 3.3.6 (PLD Linux)
OS:                Linux (i686) release 2.6.14.2-4

installed software: 
 
libmusicbrainz-2.1.2
libtunepimp-0.4.0
amarok-1.3.6 with fixed ktrm.cpp:
http://cvs.pld-linux.org/cgi-bin/cvsweb/SOURCES/amarok-libtunepimp-0.4.0.patch?rev=1.1

testcase: 
 
1). clear playlist and add a file.  
2). right click on `edit track information`.  
3). click on `fill-in tags using musicbrainz`.  
    * musicbrainz request is endless now.  
    * click `cancel` and goto 2+3 again to get info without any problems.  

it seems to a strange lock.
