Description Antoine 2012-04-09 00:00:49 UTC

Create an artistic text.
Set its height to zero with the handle on the bottom edge.
Crash.
I can reproduce easily in Krita, Words, flow and Karbon.
In calligraflow: it doesn't crash; the shape is stuck, with x,y,w and h set to precisely 138.89 inches.

It happens for me after some time after setting the with/height to 0 in the docker. And then hiding and showing the screen.

With valgrind I get the following error messages before the crash

==31728== Warning: set address range perms: large range [0x453d0030, 0x553d0050) (noaccess)
==31728== Warning: set address range perms: large range [0x953d2040, 0xb53d2040) (undefined)

and after that it seems the memory is corrupted.

Same bug as 299580 -- that report has a backtrace.
