           Summary: kmail crashes after opening a link and choosing
                    firefox as application
           Product: kmail
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: hinkelma at tcs.uni-luebeck.de


Application that crashed: kmail
Version of the application: 1.12.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.32-020632rc6-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I tried to open a link in an email. Then, kmail opened a dialog and asked me to
choose an application for opening the link. I choosed firefox from the menu and
"firefox %u" appeared in the text field. After clicking the button to proceed,
firefox showed up and kmail segfaults.

I'd like to mention the link in the mail was set like:
(Name of site, http://www.foo.bar/address/extension).
Firefox shows in its address bar:  
http://www.foo.bar/address/extension).
Thus, the site didn't show up because of ")." at the end.

I was able to reproduce the crash several times.
