alpha channel lost in conversion from TGA to PNG

Hi,

when using "convert xyz.tga xyz.png" the alpha channel is lost, even if I use -alpha on or -matte option.

I assume, that this is a bug.

Thanks

Can someone reproduce this bug, or is this just an issue of a wrong syntax ?

thanks,
Kenan

Does 'identify -verbose xyz.tga' detect the alpha channel?

If not, might be this problem where IM is not detecting alphas in certain tga's:

If it does, then might be something else..
