KMessageBox::error() seems to hang on empty message text

[Ingo Klöcker]

Hi,

I've tracked down a problem with freezing KMail (trunk) to a call of 
KMessageBox::error(). If the message text is empty then 
KMessageBox::error() hangs somewhere before the message box dialog is 
shown. To reproduce just try to run the following line
 KMessageBox::error( qApp->activeWindow(), "", i18n("Error") );

Regards,
Ingo
