nxpre.itcl gets stuck on mp3 parsing

[GoogleCodeExporter]

What steps will reproduce the problem?
1. make a test.pre-REL with mp3 files
2. use SITE PRE MP3 test.pre-REL
3.

What is the expected output? What do you see instead?
it should output the parsed id3 data and area size filecount, but instead 
it just hangs after the command, the files do get moved, but no errors in 
logs

What version of the product are you using? On what operating system?
nxtools 1.21 on windows2003

Please provide any additional information below.

the nxpre.itcl script gets stuck on this bit
when i comment this out and site pre mp3 works fine again, though without 
mp3 files parsing

    # Attempt to parse every MP3 file until successful.
    foreach filePath $mp3Files {
        if {[catch {::nx::mp3 $filePath mp3} error]} {
            ErrorLog PreMP3 $error
        } else {
            set codec [format "MPEG %.1f Layer %d" $mp3(version) 
$mp3(layer)]
            iputs "|-------------------------------------------------------
-----------------|"
            iputs [format "| Artist  : %-60s |" $mp3(artist)]
            iputs [format "| Album   : %-60s |" $mp3(album)]
            iputs [format "| Genre   : %-16s Year: %-11s Bitrate: %-16s |" 
$mp3(genre) $mp3(year) "$mp3(bitrate) Kbit"]
            iputs [format "| Channel : %-16s Type: %-13s Codec: %-16s |" 
$mp3(mode) $mp3(type) $codec]
            set isMP3 1; break
        }
    }
