Description Wonko 2011-05-30 12:33:04 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 2.6.38-pf8 x86_64
Distribution: "Gentoo Base System release 2.0.2"

-- Information about the crash:
- What I was doing when the application crashed:

I installed the new plasmoid when I read about it on KDE-Apps.org [*]. Placed it onto the desktop, resized it, then moved it into the tray. But it's barely visible there, so I dragged it to the desktop again. After this, the handle for moving, resizing, rotating etc. did not appear when the mouse was over the widget. I clicked onto it, and then plasma crashed.

I am not able to reproduce this, though.

BTW: is this the right place for reports of user-written plasmoids? Or should I directly contact the author in the future?

[*] http://kde-apps.org/content/show.php/CPU+and+System+Viewer?content=142178

The crash does not seem to be reproducible.

-- Backtrace:

Comment 1 Wonko 2011-05-30 12:38:31 UTC

The handles are gone again now. Happened when I activated 'square aspect ratio', and then deactivated it again. I did this the last time, too.
Now I can move the plasmoid, but not resize it. Oh, and now plasma crashed again, it took longer now, last time it was about instantaneous.

Comment 2 Aaron J. Seigo 2011-05-30 12:58:39 UTC

the handles issue is fixed in 4.7; usually reporting issues to the author is the best thing, but in this case it looks like it isn't in the widget that the problem exists so here is the correct place for this particular report.
