           Summary: Empty "Default Browser" launches fill x client limit and
                    freezes kde.
           Product: kde
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: paradoxin at gmail.com


Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    Gentoo Packages

Trying to launch a browser from a link, (Say for example, clicking "Open in new
browser" on a link in Xchat), caused an uncountable amount of the application
/usr/bin/kfmclient trying to access that url. 

The task bar was flooded with Konqueror applications and icons, clipping each
other until KDE became unresponsive. After 20 seconds or so, they all
disappeared, but I could not launch any new applications, with the error: 
Maximum number of clients reachedError: cannot open display: :0

xrestop showed that there were many "unknown" applications taking client slots,
with very small memory usage, as seen in the next post.

I encountered this after setting the default browser to mozilla firefox, after
installing mozilla-firefox-bin from portage, then removing that with emerge -C,
and installing mozilla-firefox. This left the Default Browser field blank,
which led to a flood of konquerors. This is always reproducible.
