When unpacking archives (rar, zip, tar, gz, ...) the process-bar in the statusbar of xarchivers just keeps going but the archive is actually already unpacked. Pressing the Stop button gives me the error: "No such process". Closing gives me the message: "Press the stop button first". So the only way to close xarchiver is by killing the xarchiver process manually. This problem is new in the latest revision because before I didn't had problems unpacking packages

Reproducible: Always

Steps to Reproduce:
1. Open an archive in xarchiver
2. Extract to location

Actual Results:  
The process indicator keeps going and there's no clean way to close xarchiver.

Expected Results:  
The archive is extracted to the desired location (that's no problem) and cleanly close xarchiver.
