Docky crashes when disconnect or reconnect power adapter to laptop

[Christer]

This is my first time reporting a bug so hopefully I get this right.

Docky crashes when I disconnect (or reconnect) the power adapter from a Lenovo ThinkPad Edge S430 with the Intel graphics activated on a fresh install of Ubuntu 14.04 x64 Desktop (Trusty Thar).

This happens when I start Docky in the terminal with the command "dock --debug" and disconnect the power adapter after a short while :

[Jerko Steiner (jerko-steiner)]

I have the same problem. As I do not use the Battery Monitor plugin, I do not need Docky to be able to react to UPower DBUS events so I downloaded the source code, commented out the SystemService#HandleUPowerChanged method body, compiled the code and now it does not crash. The reason why does it crash is still unknown to me, but at least now I can use it the same way as I used to.

[Weston Bustraan (wbustraan)]

I was able to fix it without commenting out the code.

In Docky.Services/Docky.Services/SystemService.cs, I changed:

[Interface(UPowerName)]
interface IUPower : org.freedesktop.DBus.Properties

to

[Interface("org.freedesktop.DBus.Properties")]
interface IUPower : org.freedesktop.DBus.Properties

I'm not a .NET programmer (Java), but I would hazard a guess that the proxy object that dbus-sharp is generating will only respond to the interface described by the Interface attribute. The 'Get' method is a part of org.freedesktop.DBus.Properties D-Bus interface, not org.freedesktop.UPower.

The other thing I did was to add a try/catch block around the code in HandleUPowerChanged() similar to the one in InitializeBattery(), so that even if the the D-Bus call fails, it doesn't crash all of Docky.
