Version: (using KDE 4.2.0) Compiler: gcc (Ubuntu 4.3.2-1ubuntu12) 4.3.2 OS: Linux Installed from: Ubuntu Packages I set the desktop to be a folder view. I clicked on a desktop icon. I right-clicked and clicked rename. I selected the icon text. I right-clicked on the icon text and clicked copy (pressing C-C has same effect). Desktop is replaced with gray blank screen, panel and other widgets disappear. Firefox and yakuake remain accessible (Firefox through Alt-tab or taskmanager, yakuake through its function key. Running "plasma" with krunner restores desktop and panel.(
Mh, strange situation If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)
So, I was slightly incorrect earlier: C-c does not duplicate the behavior; it just copies the file the icon represents, not interacting with the text at all. Here's the backtrace: pobocks@soundwave:~$ gdb plasma This GDB was configured as "i486-linux-gnu"...
