Application: calligrawords (2.4.1) KDE Platform Version: 4.8.3 (4.8.3) "release 501" Qt Version: 4.8.1 Operating System: Linux 3.1.10-1.9-desktop x86_64 Distribution: "openSUSE 12.1 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: In a blank document, I created a new geometric shape (e.g. a pentagon). I grabbed one of the shape resize handler with mouse and started resizing. Application crashed. This is reproducible, though it may take a while -- just move the mouse around, constantly resizing the shape. If the shape suddenly disappears (as it sometimes does), create a new shape and resize that. The crash can be reproduced every time. -- Backtrace: Application: Calligra Words (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0x7f099ce50760 (LWP 17890))] Thread 2 (Thread 0x7f0978bb0700 (LWP 17891)): #0 0x00007f099a439ff3 in poll () from /lib64/libc.so.6 #1 0x00007f0997213a98 in ??

Thanks, I can confirm but it's important to use the top left handle of the bounding box
it takes a bit of patience to provoke, and seems related to the pathshape At least I got a different bt once. Stupidly I didn't save that bt, but it was about the pathshape. Ok here goes: insert a hexagon grap a corner and drag it around the diagonally opposite corner in a circular motion. After a couple of rotations the shape disappears. release mouse undo move mouse over one of the corner handles the bt is a little bit different though: Application: Calligra Words (calligrawords), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I have investigated a bit more and it seems to be in line 317 where we might take atan2 of 0.0, 0.0 which is undefined I inserted an assert and that proves this undefined condition occurs in this kind of scenario. Thinking about how to solve

last bt is easy to reproduce - just have a pathshape then drag the bottom left corner up slowly so the height becomes 0. it's not a devision by zero, but because the interactive resizing doesn't restore the original but rather apply an inverse matrix there is an accumulated wrongness. very fast the size becomes big (shape disappears from screen) and the becomes infinite and we have the crash I tried settting the original m_oldTransform[i] but although the crassh is fixed there is something wrong with the translation

(In reply to comment #5) > last bt is easy to reproduce - just have a pathshape then drag the bottom > left corner up slowly so the height becomes 0. I get your BT only, when I drag TOP left corner downwards. For my BT, I simply added a qDebug() << rotOctant << m_angle; in DefaultTool.cpp:431 -> 17 45 17 45 17 45 17 45 17 45 17 45 -2147483640 nan -> crash, as the index for m_sizeCursors for sure is out of bounds, leading to a not-valid QCursor-Object.
for your last crash there is a fix in the attached patch - doesn't do much good though as there are just different crashes that come up. But it fixes that cursor crash.
*** Bug 297738 has been marked as a duplicate of this bug. ***
Did the fix for the cursor crash get pushed already? I seem to remember working on that as well.
I cannot reproduce the crash anymore, but I can disappear the shape completely: karbon(2751)/koffice (lib komain) KoRTree<T>::insertHelper: KoRTree::insert boundingBox isNull setting size to QSizeF(0.0001, 0.0001 Shapes _should_ have a minimum size.
Thank you for the bug report. As this report hasn't seen any changes in 5 years or more, we ask if you can please confirm that the issue still persists. If this bug is no longer persisting or relevant please change the status to resolved.
