The issue is caused by the X-Window server (or Qt). When the calendar popup is requested, it is created and want to gain exclusive focus. At the same time the editing finished signal is sent and that fires the breakpoint. This causes eric to request the mouse and keyboard inputs and we have a deadlock situation. The same happens, when setting a breakpoint in a menu handling function. This situation does not happen on every OS (e.g. doesn't happen on Windows). Therefore I don't consider it an eric issue. However, if a workaround is known, I am happy to implement it.

Please upload a small self contained sample exhibiting this issue and the traceback you get with your code. Currently I am not able to reproduce the issue.

If I did a breakpoint in the line command within the on_???_editingFinished() and run program by pressing shift+F5, the eric program will crash if I press the dropdown icon on that ??? QDateEdit. My computer is Linux 17.3 and the version from <show version> of eric program are: Python 3.4.0 Qt 4.8.6 PyQt 4.10.4 sip 4.15.5 QScintilla 2.8.1 WebKit 537.21 eric6 6.0.9 (rev. 1d7d42500f54) I tested with previous version of eric back to version 6.0.0. There was the same crash. The video I send was showing what I did before crash. I could not show until crash occur. If I edit the QDateEdit in edit line, it's find. But don't press dropdown icon.
