[Eric] Eric 4.3.0: new help tab produces exception

[Detlev Offenbach]

Hi,

thanks for this bug report. It will be fixed in the next release. The line 
raising the exception should actually be preceeded by:

if self.printPreviewAct:

because that action is only defined, if Qt version 4.4.0 or newer had been 
detected.

Regards
Detlev
