Bug#497518: khelpcenter4: Crash when doing a Build Search Index

[Matthias Weiss <matias.liberta@gmail.com>]

Package: khelpcenter4:
Version: 4.1.0-2
Severity: grave
Justification: renders package unusable

*** Please type your report below this line ***

After I installed the koffice-doc package from experimental I wanted to 
rebuild the index. I started khelpcenter via kmail -> Help -> KMail Handbook 
and in the Help Center I chose Settings -> Build Search Index. A popup appears 
and I'm marking "Application Manuals" in the "search scope" column. When I 
click on "Build Index" the Help Center crashes.
