Thank you for your bug report, I can confirm this issue for the file http://download-ln.jetbrains.com/idea/ideaIU-10.5.RC2.tar.gz on Ubuntu 11.04.
A duplicate bug had been reported for this very file -- it seems to be a strange coincidence, so maybe there /is/ something wrong with the archive... The error does not occur if you first gunzip the file and then use file-roller, also if you gzip the tar file again, file-roller can extract the resulting .tar.gz file). All that said: The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance. ** Changed in: file-roller (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/730386 Title: File Roller reports error on tar.gz extraction of known good archive -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
