XFCE 4.4 beta 2 installed. I am using the included 0.3.9.2 beta 2 Xarchiver. I have some tar.gz files that Xarchiver cannot open (says invalid format). If you like, I can try and upload it as an attachment. Using the command line tar, I can view the files just fine (tar ztf file.tar.gz).
Created attachment 658 Tar file example that cannot be opened Here's an example tar file. It is just some code examples. "tar zxf Starter.tar.gz" extracts the files successfully. Xarchiver can't even open it.
Fixed in r22414.
