Docky dies when emptying trash via Trash Docklet

[mrtwister]

Docky 2.1.0 r1572

When right clicked on the trash docklet, I get the following error, but the menu opens without any problems:

[Error 12:01:00.154] [NativeInterop] Failed to query info for '': Unbekannte Datei oder unbekannter Ordner
[Info 12:01:00.154] [NativeInterop] at Docky.Services.NativeInterop+<GFileQueryInfo>c__AnonStorey1E.<>m__37 () [0x000ab] in /build/buildd/docky-2.1.0~bzr1572/Docky.Services/Docky.Services/NativeInterop.cs:210

Then, when I click on "empty trash", docky closes and I get the following output on my terminal:

I can fix this, but I really wish I knew what exactly was causing this. That error message in German, translated I think means "unknown file or folder". Is there something abnormal about the files in your trash? If possible can you give me a ls -la of the trash folder? I can understand if you don't want to, I am asking for possibly private data, but it will greatly help me in finding out the root cause of this error.

[mrtwister (mrtwister)]

Yes, it means "unknown file or folder". I hadn't any problems with this issue lately, and I can not reproduce it anymore. The installed version now is r1620. Unfortunately I can't remember what files I had in my trash, but there wasn't anything abnormal about them. This seem already to be fixed, probably it was caused by something else, e.g. Nautilus.

@Chris S.

It happens for me regardless of the file type.

[Chris S. (cszikszoy)]

@Seung

What happens? This exact same error? Can you give me the stacktrace? It also would help if you could give me some more information about the files in your trash as well. ls -Rla on the trash directory would be very helpful.

@Chris S.
'Then, when I click on "empty trash", docky closes :' is describes what I'm experiencing.
Also I can't seem to be able to empty trash through docky when this happens.

The problem appears to be sporadic.
For me, when it happens, I try openning the trash can in nautilus.

It just becomes busy without showing anything actually inside!!

Nautilus menu ->file ->empty trash does seem to work.

I'll try ls -Rla on the trash directory the next time it happens

PS. How can I do a stacktrace?

[Chris S. (cszikszoy)]

@Seung

You need to run docky from the terminal with the -d flag, eg. $ docky -d

This is also happening for me, docky version 2.0.7 on Ubuntu Maverick 10.10

Linux jonoxps 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:36:48 UTC 2010 i686 GNU/Linux

Fixed in rev 1675.

And by 'fixed' I mean it wont crash. If this problem occurs now, Docky shouldn't crash but your trash will not actually empty! There isn't much more we can do.
