plasma-desktop (0.4) on KDE Platform 4.5.95 (4.6 RC2) using Qt 4.7.1
This backtrace might be related to this problem, although I don't use a dual-screen setup.
I was simply dragging a notes applet to the upper left corner of my desktop grid containment - I'm not sure anymore whether I moved it over the screen border or not.
I couldn't reproduce this crash.
Using:
KDE SC 4.6 RC2 (4.5.95)
Qt 4.7.1

plasma-desktop (0.4) on KDE Platform 4.6.00 (4.6.0) using Qt 4.7.1
- What I was doing when the application crashed:
I've experienced a similar issue:
- Connected a 2nd screen
- Although my laptop display was configured as primary screen in 'krandrtray', the grid desktop (and its wallpaper) I had on my primary screen before was now shown on the 2nd screen
- I've re-configured the desktop containment on my primary screen to be a grid desktop too
- I moved the RememberTheMilk applet from the 2nd to the 1st screen
- I've closed the RememberTheMilk applet
- Plasma crashed

[Comment from a bug triager] From bug 272464 (KDE SC 4.6.0): - What I was doing when the application crashed: Moving a folder view widget between the primary screen to the secondary screen. - Unusual behavior I noticed: Initially, an outright crash, which I've attached the backtrace for. Afterwards, as you cross the monitor borders to the secondary screen, the Widget fails to display on the screen during dragging and after releasing the mouse button. - Custom settings of the application: Running on NVIDIA proprietary drivers and utilizing twinview x11-video-nvidiaG02-270.41.06-5.1.i586 From bug 268433: - What I was doing when the application crashed: Dragging a widget from Grouping Desktop to Panel with auto hide. This required me to mouse over bottom of screen to show the panel and be superfast to drag the widget before the panel hid again. But with crash as a result. From bug 268424: - What I was doing when the application crashed:draggin widgets between desktops - Unusual behavior I noticed: widgets unable to be displayed on main desktop folder view setting only occupies half the desktop other half unable to place widgets. folder view widget on main dekstop just display single large icon instead of whole folder view when dragged into other monitor it is displayed correctly From bug 272359: - What I was doing when the application crashed: Drag any applet from primary to secondary screen (dual head). Plasma crash instantly, and the applet is lost (with its associated settings). First occured with "Notes", then I created a new "Favourite" and reproduced it. Using KDE 4.6.2 and plasma addons (Grid Desktop enabled), Fedora 14 x86_64 (all up to date from stable repos) on Asus V1S laptop, with NVidia GeForce 8600M GT adapter (nouveau driver). *** Bug 272464 has been marked as a duplicate of this bug. *** *** Bug 268433 has been marked as a duplicate of this bug. *** *** Bug 268424 has been marked as a duplicate of this bug. *** *** Bug 272359 has been marked as a duplicate of this bug. *** Created attachment 61155 [details]

Moving an applet across screens for dual monitors. When attempting to move any applet, plama crashes instantly and consistently.

original crash report
Hello! This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug is already resolved in Plasma 5. Accordingly, we hope you understand why we must close this bug report. If the issue described here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging Thanks for your understanding!

Application: plasma-desktop (0.4) KDE Platform Version: 4.5.95 (4.6 RC2) Qt Version: 4.7.1 Operating System: Linux 2.6.34.7-0.7-desktop x86_64 Distribution: "openSUSE 11.3 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: When using the grouping desktop containment for plasma on both of my dual monitors, if I try to drag a group from one monitor to the other it causes plasma to crash consistently. I understand that plasma cannot guarantee that there is a grouping desktop on both screens. If it is not possible to tell whether there is a grouping desktop on both screens (and thus allow dragging groups between them), at the very least it should just block the drag rather than crashing. - Custom settings of the application: It doesn't appear to matter what sort of group I use (I've tried with several types), or whether there is any widget in the group. I am using an nvidia card with twinview, but this is not a problem for normal plasma widgets or panels, both of which can be dragged between monitors easily. The crash can be reproduced every time. -- Backtrace: Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault [Current thread is 1 (Thread 0x7fb2032a27a0 (LWP 10792))] Thread 2 (Thread 0x7fb1e8fb0710 (LWP 10793)): #0 0xffffffffff600177 in ??
