Label with install status not updated

Reproducing the problem:

Open F-Droid
Select the Available tab
Select "All" in checklist
Select "1x1 clock" (or any other app that is not installed)
Click the "plus in a circle" icon on top
Click "install" at the bottom
Wait for the install to complete

The text on screen reads

Available
1x1 clock
Not installed
Clock widget
Small 1x1 clock widget
Version 1.2.2
Installed
Added on 12/20/2014

The same screen says "Not installed" and "Installed". The upper label is wrong, as the installation has been successful.

Now wait for the system to go to sleep. Wake it up. "Not installed" becomes "Version 1.2.2 installed". Apparently the label wasn't redrawn upon installation but the sleep caused it to be redrawn.

I'm using Samsung Galaxy S4, CyanogenMod 11-20150104-NIGHTLY-jflte, Android version 4.4.4, F-Droid 0.78.
