"Unable to build image" error - how to translate?

I got one of these while doing a "Build all thumbnails and resizes".
It would be a really great help if the error message actually mentioned the image causing the error.

How does one translate the error messages into a path and file name?

 Error (ERROR_PLATFORM_FAILURE)in modules/netpbm/classes/NetPbmToolkit.class at line 413 (GalleryCoreApi::error)

Request variables: Array
(
    [view] => core.DownloadItem
    [itemId] => 1469
    [serialNumber] => 2
)

OK, any way to translate this to something I can understand?
Say, a file name?
