I've been able to reproduce this bug consistently with Empathy and Skype (latest Oneiric). Just open one of them normally, then click the red X to hide it to the indicator or tray. When you open them again via the indicator or tray, this bug occurs.
I've attached my xsession errors from a session where I reproduced this with empathy. I believe a pertinent set of lines is: ** (compiz:1678): DEBUG: TrayChild Rejected: Empathy empathy Empathy ** (process:1814): DEBUG: server_display at 986837 ** (process:1684): DEBUG: zeitgeist-datahub.vala:174: Inserting 1 events ** (process:1814): DEBUG: server_display at 990844 ** (process:1684): DEBUG: zeitgeist-datahub.vala:174: Inserting 1 events ** (process:1814): DEBUG: server_display at 994548 ** (process:1684): DEBUG: zeitgeist-datahub.vala:174: Inserting 1 events ** (compiz:1678): WARNING **: Unable to fetch children: Method "Children" with signature "" on interface "org.ayatana.bamf.view" doesn't exist ** Attachment added: "Xsession errors shortly after reproducing this bug with Empathy" https://bugs.launchpad.net/bamf/+bug/767079/+attachment/2169635/+files/.xsession-errors -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/767079 Title: raising the un-pinned windows from the launcher shows the app icon twice To manage notifications about this bug go to: https://bugs.launchpad.net/bamf/+bug/767079/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
