SUMMARY
The "Rescan project files" button causes a popup that displays progress as files are loaded into translation memory. The popup never disappears once loading has finished.


STEPS TO REPRODUCE
1. Open Lokalize translation project with a file to translate (I tried with .xlf data)
2. Click "Translation Memory" tab
3. Click "Rescan project files" button

OBSERVED RESULT
Data is processed like normal and the progress bar on the notification moves to the end, but at 100% complete the notification doesn't timeout and disappear. Instead to get rid of it you have to press the square icon (stop button), though I don't think this stops anything, because the process has already completed.

EXPECTED RESULT
Notification hides after processing files.
