Version:           3.3.1-1.1.2.kde Red Hat (using KDE 3.3.1-0.2.2.kde, Fedora Core release 2 (Tettnang))
Compiler:          gcc version 3.3.3 20040412 (Red Hat Linux 3.3.3-7)
OS:                Linux (i686) release 2.6.8-1.521

I just upgraded to kde 3.3.1 and have experienced the following 
weirdness in konqueror. When using konq as a file manager, if I switch the view from "Icon view" to "Detailed List view" the bookmark toolbar appears. This had never happened before the upgrade to 3.3.1.

After some more investigation I determined the following pattern can re-create the occurrence on my machine. I have the bookmark toolbar enabled in my web browsing profile, but not in the file management profile. If I first open konq as a web browser, close it, and then open up konq file manager and switch from icon view to detailed list view, the bookmark toolbar appears. I can then go to settings->toolbars and deselect the bookmark toolbar. The bookmark toolbar will no longer unexpectedly pop up in file management mode. That is, until the next time I decide to use konq in the web browser profile, and then the whole process starts over.
