multiple instances or double icons of application detected on bamfdaemon respawn

[Didier Roche]

Doesn't happen 100% of the time, but quite easy to tackle:
test case

1. start a non pinned app e.g. system monitor
2. open terminal and type 'killall bamfdaemon; /usr/lib/bamf/bamfdaemon

What happens:
you see two icons of system monitor in launcher

-> This case is fixed, but:
For example, try to run an application with no desktop file (i.e. Xclock, valkyrie...) then kill bamfdaemon: the icons will be duplicated.

I just using mail client - thunderbird, I close it. When I open thunderbird again, next icon appears in unity, while both icons forwarding to this one instance of thunderbird. After right click on the icon in unity panel, there is blank line instead app name on the newly created icon. I guess it'll happen with more apps.

Another case:
TEST CASE:
1. open a single instance of an application
2. killall bamfdaemon
 -> when bamfdaemon will respawn, 2 arrows will appear on the launcher, alt-tab think there are two instances as well.
Not that in 5.4, some icons are doubled (no more double arrows)

Unity Issue test case:
1. Open gnome-control-center
2. killall bamfdaemon

libbamf issue test case:
1. Open xclock
2. killall bamfdaemon

expected:
 -> when bamfdaemon reconnect, only one instance in launcher/alt+tab is seen.

Would this definitely be fixed for Unity 5.4? It is happening very frequently thereby messing with the alt-tab.

[Omer Akram (om26er)]

I think its in 11.10 as well? a backport for 11.10 would be highly welcome as well.

[Federico Raimondo (fraimondo)]

I can confirm this bug happening in up to date ubuntu 12.04

[Didier Roche (didrocks)]

still here in 5.6

[Didier Roche (didrocks)]

Can't reproduce in 5.8. Closing ;)

[Marco Trevisan (Treviño) (3v1n0)]

Didier, it still can happen.
For example, try to run an application with no desktop file (i.e. Xclock, valkyrie...) then kill bamfdaemon: the icons will be duplicated.

Settings verification-done since the original issue is fixed and there is no regression, some cases are not solved and the bug should be reopened once the update is to precise-updates though

Awesome. Wouldn't that be a different bug entirely though? It seems to
me that if one fix only fixes half the reports, then there were actually
two bugs.

[Sebastien Bacher (seb128)]

yes, having a new bug about the other issues would probably be easier than abusing the current one with side issues
