Description anidev 2011-09-15 22:57:30 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.7-desktop i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
First, I just want to say that Plasma on my laptop here (OpenSUSE 11.6) seems very buggy: going to panel settings does not darken existing spacers and makes it hard to resize them; adding new spacers darkens it properly and I can resize them properly, but the darkening does not go away after exiting panel settings, notifications widget has a lot of problems, etc.
- What I was doing when the application crashed:
I accidentally messed up the order and spacing of my icons in one of my panels (by dragging to a vertical screen edge to test it and dragging it back to a horizontal edge), so I set about fixing it. As I said above, spacers were a problem - I couldn't see them, and the cursor showed the resizing cursor only half the time. Notifications widget wasn't displaying anything (it had a number "1" on it, but clicking it and double-clicking it did nothing), so I tried to remove it and add it again. First time, a dark space appeared but did nothing (it got placed in the wrong location, and I couldn't move it because Plasma couldn't "see" it), and disappeared after I resized another spacer; tried again, found the right place, let go of the dragging, and Plasma crashed.
