Indicators don't work on lxpanel

I ran into the same issue earlier when attempting to port indicator-applet to gnome 3. I updated configure.ac to depend on the newly renamed indicator-0.4 but I forgot to update INDICATORDIR and INDICATORICONDIR. I'll attach a patch that fixes it.

Works with all the -gtk2 indicators except indicator-appmenu-gtk2 and indicator-me-gtk2. If either of those are installed, it will fail to load successfully.

Thanks Jason, I confirmed that it's working well :)
If you can do a debdiff, I'll be glad to sponsor it for you. Otherwise, I'll add your patch to the package later.

Sure, he's my attempt at a debdiff. Let me know if I need to change anything. Thanks.

Thanks :) I'll merge it in the next upload. Next time, please also add the syntax to close the bug in debian/changelog ( LP: #819528 for this case).

this bug appears again in 0.5.8-1ubuntu3

LXPanel 0.5.8-1ubuntu3 here (Lubuntu 11.10 - 32 bit) and I had "No Indicators" message. I installed these:

indicator-session - 0.3.7.1-0ubuntu1.1
indicator-session-gtk2 - 0.3.7.1-0ubuntu1.1
indicator-weather - 11.05.31-0ubuntu2.1

And I don't have that message (No Indicators) anymore. However, I was trying actually to do something just like GNOME 2.xx which is displaying the Username who is logging in to the current active session. Now, all what I have is an icon for a Black Monitor and when I click on that, I get the same list that we can see on Ubuntu 11.10:

System Settings
Display
Startup Applications
Updates Available
.
.
.
etc

So, how can I just add the username to this? and how can I just add the weather to it like GNOME 2.xx in Ubuntu 10.04?

Not sure how/where to report this as it seems I can't file a bug without Apport...

Since Quantal (12.10), almost every indicator has dropped support for GTK2 and thus are not usable with LXPanel Indicators. A solution for this would be to either port lxpanel & lxpanel-indicator-plugin to GTK3 or maintain GTK2 versions of the Ubuntu indicators.
