Package: xdrawchem
Version: 2.0-2
Severity: normal
Hi there!
Under certain circumstances (which actually happen a lot) xdrawchem
hangs when doing "Undo" (be it via the Menu or via Ctrl+Z, it doesn't
matter) and has to be killed. It seems that the hang always happens when
the "Undo" operation would lead to a non-empty worksheet (meaning:
almost always!). Once hung, the program uses 100% CPU load of one core.
Steps to reproduce:
* Start up xdrawchem.
* Add 2 lines by doing the following:
* Activate the line tool by clicking on the icon depicting a
straight, continuous line in the toolbar (tooltip text: "Draw Line").
* Draw a line on the worksheet.
* Draw a second line on the worksheet.
(It doesn't matter, if it's connected to the first line or not.)
* Undo the last action by clicking the menu "Edit" -> "Undo"
* Verify that the GUI doesn't respond any longer.
Terminal output between clicking "Undo" and hanging:

Compiling Qt and xdrawchem both with DEB_BUILD_OPTIONS="noopt nostrip" I
was able to get meaningful stacktraces. As the thread is still active
(but probably in an infinite loop), those stacktraces vary, a "typical"
one looks like this (from #4 on below they are always identical, the
frames #0 to #3 may be different in other cases):
