-- Information about the crash:
I have a "Windows Script 5.6 Documentation" in CHM file "script56.chm"
downloaded from microsoft's web site. When I open it the okular shows his
content normally but crashes after few pages. The length of script56.chm is
1351013 bytes and it contains about 1192 html parts.

The crash can be reproduced every time.
