I think problem is in fact that in 5.5.2 WIP 20100305 hyperripper writes big amount of false mpeg detection messages into log text field. there are thousands of "Found mp3 @ xxxx (0bytes)". depending on file and file contents it will mostly work, but sometimes it will crash with error i copied above. crash will happen more often if file is longer.

sample file which will show this behaviour is attached (i created it myself to show this problem so don't expect any sense in it). decompress before trying :)

when i hide log in main windows crash doesn't happen anymore also it seems that to make crash happen you have to put some other window on top of dragon unpacker and then make dragon unpacker active again. as long as its hidden crash will not happen

I was able to reproduce, but I don't know what is the problem. Anyway, I want to get rid of the current log to replace it by a VirtualTreeView, I might do that for v6.0. Instead I added code to speed up MPEG Audio search when the found entries do not match the minimum frame numbers & size. I also introduced a way to not display so many found mp3 messages.

You can check this with this wip version: http://download.elberethzone.net/dup5/wip/55210/dup552wip20100421.7z

I will submit the changes to CVS asap too.
