Package: xdrawchem
Version: 2.0-2
Severity: normal
Hi there! :-)
The xdrawchem executable crashed with a segmentation fault every time
you leave the tool to insert text (no matter if you've entered text or
not). Steps to reproduce:
* Startup xdrawchem
* Close the "welcome" dialog (if it appears) by clicking OK
* Switch to the text tool by clicking on the "T" icon (description
"Draw or edit text") in the toolbar
* Click on an empty place in the document to start inserting text
* Switch back to the selection tool by clicking on the cursor icon
(description: "Select") in the toolbar
-> Crash with segmentation fault
The last output of the program on the console before the crash is:
addText
0
screen
paintEvent painter begin
drawAll: Drawable(0x14493d30)
Text::Render begin

I installed the Qt debug symbols package and compiled xdrawchem from
source with "DEB_BUILD_OPTIONS=nostrip" in order to get a reasonable
backtrace. Here it goes:
