docky freezes upon removing "bookmarks" docklet

[Bernhard]

In rev 1052, docky crashes whenever I want to remove the bookmarks docklet, either in "docks" tab or in "docklets" tab.

You're going to have to post docky's output by running docky from terminal because this is definitely not crashing docky here

[Robert Dyer (psybers)]

mahfouz, you should know better. Post a stack trace or else I am marking this invalid. :-)

[Bernhard (b.a.koenig)]

Of course I know I shld attach a debug but I didn't really get a debug, it's not crashing actually, it's freezing. Here's what I get when I "add bookmarks" then "remove bookmarks":

[Info 20:51:59.540] [PluginManager] Loaded "Bookmarks".
[Debug 20:51:59.545] [BookmarksItemProvider] Updating bookmarks.
[Info 20:51:59.559] [DrawingService] Could not find 'folder-home', using fallback of 'application-default-icon'.
[Info 20:51:59.570] [DrawingService] Could not find 'folder-home', using fallback of 'application-default-icon'.
Bookmarks state: False
[Info 20:52:10.210] [PluginManager] Unloaded "Bookmarks".

[Bernhard (b.a.koenig)]

OK, first I thought it might be the icon theme but even if I use the default "humanity", I get:

[Info 20:56:05.016] [PluginManager] Loaded "Bookmarks".
[Debug 20:56:05.020] [BookmarksItemProvider] Updating bookmarks.
Bookmarks state: False
[Info 20:56:06.476] [PluginManager] Unloaded "Bookmarks".

and full freeze of docky.

[Robert Dyer (psybers)]

Ok if it isnt crashing then you need to get us a trace of where it is freezing.

kill -SIGQUIT pid_of_docky

should dump out a trace onto Docky's terminal (NOT the terminal you run the command from!).

[Bernhard (b.a.koenig)]

This is suddenly working now. Wonder if somebody fixed it.....

Thx!

[Robert Dyer (psybers)]

You seem to have a number of weird bugs that no one else can reproduce and that suddenly 'fix themselves'. I wonder if perhaps you have a hardware problem you arent aware of (bad memory can do very odd things but still seem 'normal', or a bad hdd).

[Bernhard (b.a.koenig)]

No, I'm just a very considerate beta tester that lives on the edge. Crappy hardware is just a part of it. :)
Seriously, I tried again and got a backtrace this time:

[Dmitry Murat (dmitry-murat)]

I can confirm this issue @ 9.10 x64. When killing it from another terminal window with 'killall docky' I get error message:

[Error 16:47:00.358] [DesktopItem] Could not find file "/usr/share/applications/openoffice.org3-startcenter.desktop"

So I think the problem is in some non-existing files that are linked to bookmarks.

[Dmitry Murat (dmitry-murat)]

Nope. Removed that shortcut but nothing changed. Docky still freezes on bookmarks docklet removal. My thread dump:
