running applications without an icon use a blank icon

Thank you for taking time in filing the bug to make ubuntu better.
1).is this bug reproduceable?
2).than describe the steps to reproduce it.
also attach a screenshot of the bug.

Steps to reproduce:
1. install an application without an icon (e.g. Sigil);
2. press the Dash Home button on the launcher;
3. type the application name in the search bar.

NOTE: Here, dash uses the standard document icon; it should use the standard application icon [see dash.png].

4. run the application.

NOTE: Here, launcher does not use an icon; it should use the standard application icon [see launcher.png].

5. press Alt+Tab to bring up the task switcher.

NOTE: Here, the task switcher does not use an icon; it should use the standard application icon [see task-switcher.png].

This bug is 100% reproducible, and occurs with more than one application.

i have also seen this with the libre office but it was white not black.but this bug is present.

thanks for your bug report. Is that still an issue in Ubuntu 12.04? Can you please test that and let us know?

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 772986, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

This is actually a different problem then bug#772986....while it exhibits the same problem a blank icon. This one happens when the *.desktop files them selfs do not contain an icon.

Bug#772986 seems to me most likely caused by a reference counting problem.

Hello Reece, or anyone else affected,

Accepted unity into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/unity/5.18.0-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

With the combination of unity now in -proposed and the related bamf update in ppa:unity-team/sru, the issue is fixed and no blank icon is shown. Instead, a generic icon is used.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

    - Launcher: start the drag icon request from the original mouse-down
      position. (LP: #858540)
    - Ignore transient unmmaped windows on minimize/unminimize
      (LP: #929712)
    - Fixes alt+tab losing focus when alt+tabing to quickly due to ubus
      being to slow to send a message (LP: #1035628)
    - If no icon is found then use the default one. This will cause all
      blank icons to be a '?' icon (LP: #886778)
    - Use GMountOperation in g_volume_mount. GMountOperation provides a
      mechanism for interacting with the use. (LP: #713432)
    - Do not reuse the menu entries if their order changes (LP: #1062283)
    - BamfLauncherIcon: ensure the icon and name values when the running
      state changes. This avoids to get "?" icons. (LP: #772986)
    - Use linear filtering to draw icons (when needed). (LP: #1036231)
