getting plugin com.getdropbox.dropbox.garcon interrupted when open NSOpenPanel

Question

I'm getting this messages on the console when I open a NSOpenPanel and then my application crashes:

plugin com.getdropbox.dropbox.garcon interrupted
plugin com.getdropbox.dropbox.garcon interrupted
Unable to setup extension context - error: Couldn't communicate with a helper application

And in the debugger I get an warning on the Thread 6 saying this:

Queue: com.apple.NSXPCConnection.user.com.getdropbox.dropbox.garcon.apple-extension-service(serial)
    0_dispatch_barrier_async_f
12 start_wqthread
Enqueued from com.apple.NSXPCConnection.user.com.getdropbox.dropbox.garcon.apple-extension-service (Thread 6)
0_dispatch_barrier_async_f

I tried everything openning my NSOpenPannel with [openPanel runModal] and [openPanel beginSheetModalForWindow:...

I use NSOpenPanel just to open a txt file

What can I do to stop get this message and application stops crash?

The App is not sandboxed and code signed. I just trying only in the Debug-build because I don't have an apple developer account. The Mac OS X version is 10.10 and the dropbox version is 3.0.3

Please add following Information to the question to find the cause of crash: Is you App sandboxed (influenced XPC)? Is your App code signed (influences OpenPanel)? Is it only in the DEBUG-Build? Do you open/run the Panel from main-thread? Which OS-Version? Which version of DropBox? — mahal tertin
We (Dropbox) would be happy to take a look at this. Can you please open a ticket at dropbox.com/support , then copy me your ticket ID (found at dropbox.zendesk.com )? I'll route it to the right people. Thanks! — Greg
@Greg Any update on getting this solved? Happens in Xcode for me too. — Thomas Krajacic
I don't believe we ever heard from the original developer here and so weren't able to sort this out. Please feel free to open a ticket yourself and copy me the ticket ID and I'll get this to the right people. Thanks! — Greg
@Greg I too am seeing this bug as well now. Did this person ever open up that bug? I'd be happy to myself if need be. — P.M.

So I had the same problem while working with Python. I think its a problem with the Finder integration of Dropbox in Yosemite. I am guessing you are using Finder (for selecting files, etc.) in your application.

Disabling the Finder-Dropbox integration worked for me:

Go to Dropbox icon > Cog wheel at the bottom left > Preferences
Disable "Enable Finder Integration"

I don't know if there is a proper way to solve this as of yet, but this workaround seems to work.

My versions: Dropbox 3.0.3, Yosemite 10.90
