[Interest] "kwallet open icon" sticks to mouse pointer after updating to Qt 4.8.7?

[René J.V. Bertin]

Hi,

Since a couple of days I have a "kwallet is open" icon stuck to my mouse pointer after having unlocked a KWallet, disappearing only when the wallet gets a timeout and is closed.
There have been no updates to the KDE libraries involved with KWallet management, but I did install the Qt 4.8.7 snapshot. Is it possible something changed in Qt 4.8.7 (compared to 4.8.6) that could explain this issue?

Thanks,
R
