cantata 0.9 unstable with kde sc 4.9.4 (arch linux)

Question

What steps will reproduce the problem?
1. start cantata
2. connect to mpd (either manually, or automatically)

What is the expected output? What do you see instead?

I expect cantata to run as advertised (which it does with kde 4.9.3). However, 
with KDE 4.9.4 it either:
* crashes silently
* crashes partially, leaving an icon in the systray (and working systray 
controls) but no possibility to open a window
* works (on rare occasions)

NB., this happens both for repo-supplied canata and for cantata compiled from 
source, both with 0.9.0 and with 0.8.3

cantata-qt (without KDE deps) works as expected with KDE 4.9.4

Please provide any additional information below.

Answer 1

So, 0.8.3 also crashes? Does it crash if you use another style apart from 
oxygen? e.g. plastique? QtCurve?
