Description parand 2009-02-05 02:14:51 UTC
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.

Comment 2 Morten Sjoegren 2009-05-03 22:31:27 UTC
I can confirm it bug on kubuntu 9.04 with KDE4.2.2.

The problem also exist is the alternative browser isn't valid (doesn't exist)
Comment 3 Magnus Bergmark 2009-08-19 23:03:19 UTC
I, too, can confirm this on Kubuntu 9.04, KDE 4.3.00. The browser command blanked itself out when switching from Firefox 3.0 to Firefox 3.5 on Kubuntu, so this can happen to a lot of people.

Always reproducible and makes the session unusable to less knowledgeable people.

I propose moving this up in severity (since clicking a link may force a user to log out). Platform can also be changed from Gentoo Packages.

IMO, a dialog should pop up saying "Cannot find your specified browser: 'xxxx'.
[ Try again ]  [ Open in Konqueror ]  [ Don't open ]"
