After unpinning launcher icon, launcher icon not shown for next program start

[Hernando Torque]

Binary package hint: unity

Difficult to describe, just try it yourself:

1. Remove a pinned launcher icon of a not running application.
2. Start the corresponding .desktop file (I used the Ubuntu logo link to /usr/share/applications).
=> The program starts, but no launcher icon shows up.
3. Quit the program.
4. Start the corresponding .desktop file again.
=> The program starts, the launcher icon shows up.

If you do 1. while the program is running (and quit), then the launcher icon will correctly show up in step 2.

I tried the steps provided and did not encounter the bug. This bug was supposed to be fixed in the 0.2.66 release of BAMF, which you seem to have...

[Jason Smith (jassmith)]

Just reproduced it, sneaky bugger. Will check it out.

[Jason Smith (jassmith)]

Caused by UnReference not running destructors. Investigating

[Jason Smith (jassmith)]

Bug is fixed in jays nux branch. When it lands this bug dies.

If you mean lp:~canonical-dx-team/nux/nux.file-renaming - this doesn't seem to work reliably. The only pattern I've found: it fails the second and fourth time after a boot - else it seems to happen randomly.

So it's:

* Boot
* Launch
* Pin
* Quit
* Unpin
* Launch
=> shows up
* Pin
* Quit
* Unpin
* Launch
=> doesn't show up
* Quit
* Launch again
* Pin
* Quit
* Unpin
* Launch
=> shows up
* Pin
* Quit
* Unpin
* Launch
=> doesn't show up

Indeed a sneaky bugger. ;-)

Still happening with unity 3.2.12-0ubuntu2.

[Hernando Torque (htorque)]

For the record: 3.6.0-0ubuntu2 - still happening.
