            Bug ID: 314456
           Summary: Crash while opening a .chm file.
    Classification: Unclassified
           Product: okular
           Version: 0.15.4
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: benoit.leffray.kde at gmail.com

Application: okular (0.15.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

Tried to open the following path on my local hard drive:
/home/ben/Downloads//[Jasmin_Blanchette,_Mark_Summerfield]_C++_GUI_Prog(BookFi.org).chm.
I simply downloaded it via rekonq and then got a notification in the KDE panel
saying that the download was finished and the above URL was clickable in the
Notifications widget (KDE panel). I just clicked on it and Okular got
automatically invoked by KDE (I didn't do anything for this.) Then I got a
pop-up windows with the error message: 'Malformed URL'. This pop-up kept
re-opening when I closed it.  
So I right-clicked on the panel to close okular more forcefully and then I got
that crash.

Notice: If I navigate to the directory '/home/ben/Downloads/' with Dolphin and
then click on the file to open it, Okular then opens the file normally and
displays its contents as expected.

100% reproducable.
