The patch is against the 4.2 branch, initial testing shows it fixes the problem for me.

Comment 5 Jannick Kuhr 2009-03-16 12:18:51 UTC 
Same here on openSUSE with 4.2.1. Downgrading Qt to 4.4.3 fixed it for me. Possibly a Qt 4.5 issue?

Actually, this is a documented behaviour change (see comment #1), so please forward port to trunk.

ok, thanks for pointing this out
