Mp3Tag v2.43 under wine 1.1.18 crashes while displaying the tracks found using
the Tag Sources feature.

Steps to reproduce:

0. Download and install Mp3Tag v2.43 from
http://download.mp3tag.de/mp3tagv243setup.exe
1. Open a directory with some mp3 files
2. Select one file in the file view
3. In main menu, click on "Tag Sources -> Amazon.com"
4. Enter "Avril"
5. Select album "X-Posed"
6. Click "Next"
7. The results windows pops up and Mp3Tag crashes right afterwards

Tested on Gentoo Linux with both wine from repository and the current git
version built with default settings.

> Mp3tag uses the Listview control in callback mode where items are not

> should ask back if it wants the text for a given item/subitem combination 
> (text set to LPSTR_TEXTCALLBACK and mask to LVIF_TEXT | LVIF_PARAM when 
> adding items). The application then handles the LVN_GETDISPINFO message and 
> provides the text only if necessary.

> also sent for Listviews which have no columns at all. Since the album you've 
> used for testing doesn't contain any title information on Amazon side, no 
> column was added to the tracks list -- but Wine asked Mp3tag to display text
