The xfce "indicator plugin" keeps crashing with almost all apps. However I need it. I just want it to keep trying to restart itself automatically (preferably every 10 seconds) instead of displaying this annoying message Plugin "Indicator Plugin" unexpectedly left the panel, do you want to restart it?
Does anyone have an idea about how to do this?
You could always remove the indicator and use the native XFCE notification area... I've found the indicator plugin under XFCE to be a pain to work with.
I had a similar problem and found a bug report with a workaround that seems to do the trick. The workaround is as follows. I modified it a little so that you don't need to actually right click the active indicator panel, which could be tricky if it keeps crashing.
Panel -> Panel Preferences
The screenshot below shows how what these menus should look like.
I spent a few hours on pages like this as I've had a problem with it instantly getting the 'unexpectedly left the panel' error as I try to execute the Indicator Plugin, with no way of accessing the settings.
I had compiled gtk3.12 earlier, which seemed to be the root of the problem. Luckily I hadn't nuked the folder from my trash, and restoring it and running
sudo make uninstall
from the gtk3.12 compile folder fixed it. On the off chance someone did the same or similarly, I might save a few hours of headaches and frustration.
