Description Dima Ryazanov 2005-12-15 03:26:06 UTC

Version:            (using KDE KDE 3.5.0)
Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 4.0.2 (Gentoo 4.0.2-r2, pie-8.7.8) 
OS:                Linux

I go to plugin settings, click scan for new plugins, then change some setting, e.g. "Enable plugins globally", "CPU priority", etc.

When I click Ok or Apply, Konqueror crashes:

Comment 1 Tommi Tervo 2005-12-15 09:23:06 UTC

Cannot reproduce

Comment 2 Dima Ryazanov 2005-12-15 09:48:07 UTC

Ok, I think I've figured out what's needed to reproduce it.

In Plugins settings, go to "Domain-Specific Settings", and add an entry e.g. "slashdot.org", "Reject".

Then, scan for plugins, change some setting, and apply it.
It should crash now.

(I can reproduce it starting with no .kde directory.)
