Not sure if that is the same issue but there was a number of stability fixes in newly released xfce4-indicator-plugin-1.0.

When I logouted, xfce4-indicator-plugin crashed with SIGSEGV in g_type_check_instance_cast() .

My crash just happened when I logged in! (-:

Even without a crash, the audio volume control widget consistently hides the drop down output when I click on it.
In effect, the xfce4-indicator-plugin audio widget is totally unusable.
Work-around: Copy the Pulse Audio Volume Control widget to Panel 0 (awkward but functional).

Could this be related to https://bugs.launchpad.net/ubuntu/+source/xfce4-indicator-plugin/+bug/1181134 ?
In that report, it seems that an executable was not specified in the correct folder.

first off, Richard, I think you meant to reference a different bug report. You just referenced this one.

fwiw, I get this crash when I try to run `sudo service networking restart`
tested on my main install, and a vm

Daniel,

You're correct. Pardon my loop! I meant to reference this one: https://bugs.launchpad.net/indicator-sound/+bug/1208204 .

In message #5 of #1208204, Daniel Letzeisen specified a patch that fixed both symptoms for me (crashing ceased and volume control item now works). I believe that it has to do with the fact that the indicator-sound-service was specified incorrectly and, hence, never invoked.

Re: /usr/share/dbus-1/services/indicator-sound.service referenced in report #1208204

I set the above file back to as it was originally installed with package indicator-sound under saucy:
          Exec=/usr/lib/x86_64-linux-gnu/indicator-sound/indicator-sound-service

Both anomalies return repeatably:
          * "xfce4-indicator-plugin crashed with SIGSEGV in g_type_check_instance_cast()"
          * Symptoms of report #1208204

Then, I used the suggested patch:
          #Exec=/usr/lib/x86_64-linux-gnu/indicator-sound/indicator-sound-service
          Exec=/usr/lib/indicator-sound-gtk2/indicator-sound-service

Both anomalies go away. The indicator-sound package will eventually be formally fixed in saucy. Until then, you could try using the patch to see if your crashes go away.

This problem also occurs for me immediately after using Shutter to take a screen capture.

I applied the fix in 1208204, and this is still present for me. Not sure if I'm supposed to be able to `sudo service networking restart`, but I still can't.

This but if affecting me on Xubuntu 14:4 (upgraded from 13:10 -- where the bug did not affect me). It crashes constantly if I try and open LibreOffice, and it crashes a lot if I open Firefox. This constant crashing leaves the system very unstable and virtually unusable (as the crash warning dialogue keeps grabbing screen focus).

I can leave the applet closed, but then I lose access to the network manager applet, and it does not seem possible to add this to the panel otherwise.

Let me know if you need any further information from me!

It's the same for me on Xubuntu 14.04. The indicator pludin crashes every time when pidgin get focus (and there are many other "sensitive" application, not only pidgin), but it's fine with firefox, terminal and many others. It's practically unusable in this state.

I'm seeing the same issue as qji , pidgin crashes the indicator app when it gets focus.
I even tried 'hiding' the messages icon in indicator-app. 14.04 upgraded from 12.04

Was crashing for me when exiting Firefox or VLC. Turned off the "Application menu" feature and it seems more stable. Might be fighting with Firefox trying to show a menu bar that Firefox is trying to hide.

Crashing for me when I open or switch focus to an xfce4-terminal (14.04 upgraded from 13.10 from 13.04 etc.)

Confirmed, shutting off the 'application menu' fixes my issues with pidgin.

Steps:
1. Right click the Indicator-application
2. Left click on 'Properties'
3. Select 'Application Menus (Global Menu)' by checking the 'Hidden' checkbox.
4. Restasrt the Indicator-application (this is easy, just pullup your app that is crashing it).

Does anyone how to enable the "global menu" indicator? I am trying to reproduce this error and so far I cannot make the global menu appear in the properties dialog.

I think that in order to be able to enable the global menu you have to have the libappmenu.so file. I'm not sure but maybe it's only installed with Ubuntu and not XUbuntu? Anyway, it's provided by the indicator-appmenu package.

Crash was reported against a now outdated version. Closing.
