Bug 475030

First, I moved a lot of data to an external hard drive. This got cancelled, because I went away and the system entered standby mode. That's all fine with me, but when I started the laptop again and searched in my folders (in split view) what had been moved and what had not, at one point dolphin crashed with the following debug info:
```
Application: Dolphin (dolphin), signal: Aborted
