Bug 193641

Version:           4.2.86 (using KDE 4.2.85)
OS:                Linux
Installed from:    SuSE RPMs

after release of KDE 4.3 beta 1 i changed repositories from UNSTABLE to FACTORY (that's where 4.3 resides now, i believe). everything works fine, except that right-clicking on the desktop and some but not all widgets causes plasma-desktop to crash with the following debug message:

------------------

i confirmed package integrity (via yast) and double-checked if all packages have been updated, but couldn't find any errors in my installation.

i noticed that, when editing desktop settings (via the diamond), the options for desktop activity -> type (desktop, folderview) don't exist anymore: the dropdown is blank. (i'm not using folderview as activity type.)
