I got this error when I am using the Spotify for Linux preview. At time the spotify icon will appear twice in the notification area. After clicking on one of them wingpanel will crash and then restart with only one icon. I have been able to replicate the bug through normal use three times so far.

[ahilles107pl (ahilles107pl)]

I have this same issue as Zach Trott.

[pyriand3r (pyriand3r)]

Same as Zach: Spotify icon doubled. Clicked both of them. With the second one no menu appeared but wingpanel crashed and restarted with a single icon.

[Charnita Fance (mrs-z)]

Yep, same thing as everyone else.

[vassilis karamitros (ecatodarcus)]

Ohhh i see we are plenty fellows with the same exact problem! hehehe!
i had the same exact problem as Zach, and the rest, described!
clicked the one of the two spotify icons, something blinked then only one spotify icon in the indication area and everything was working ok again.
just the error report came up but not another fuctioning problem.

[Samu Nuutamo (carbon)]

I was recording a video for another wingpanel crash and I was able to catch this on video. Spotify creates "ghost" indicators which cause the wingpanel to crash when activated.

Here's the video: http://funkd.org/~samu/wingpanelcrash.ogv

[Arden (highdruid101)]

Ditto! Same issue. Not to mention that the icon that Spotify creates is a bit fuzzy on my end.

[Alexandre Liscia (alexandre-liscia)]

Just had the same issue. I think it started with Synology Cloud Station app.

[falvick (falvick)]

The same issue with spotify but also when I wake my laptop from sleep.

[Thomas Citharel (tcit)]

Same issue with Spotify closing after it automatically launched.

[Thomas Citharel (tcit)]

Still same problem, when opening spotify.

[Vladimir Pissarev (l-root-8)]

Same using spotify from spotify ppa.

[Vladimir Pissarev (l-root-8)]

I found temporary solution.

Spotify is using sni-qt package to show indicator. Removing that package will disable indicator but this solution will affect other Qt based applications like Skype. Now panel not crashing on spotify start.

I was able to reproduce this bug with Spotify, and it was addressed at revision 200. The fix has already been released as an update.
