Hi, I tried reproducing your issue, and wasn't successful, no crash happens. I have OSX 10.11.5, Official Qt 5.7.0, only two languages installed, British and Myanmar-QWERTY, and I'm using the auto-generated Qt-Creator QMainWindow example.
After launching the application, I try to switch the languages around with hotkey, with clicking in the top-right language corner, and by changing the language directly in System Preferences -> Keyboard -> Input Sources. No crash is happening. What am I doing wrong? Regards, Alex. On 19 Aug 2016, at 20:13, Timothy W.

I guess that points to bugs in Qt itself and lets Phil Thompson at riverbankcomputing off of the hook! If not here, where should I report the problem? Sample program below followed by some error reports. The errors occur when switching back and forth between 'British' and 'Myanmar-QWERTY' in system preferences in OS X.

(Just create an app with Qt Creator and run it. As far as I understand, you use QWidgets, right? If so, create an empty QWitgets project, run and see how it goes.)

'Myanmar-QWERTY' is the only input source that I'm having trouble with; all others that I've tested so far appear okay. The windows version of the application also seems okay. My application is fairly complex, but I'm seeing this issue even with an absolute minimal app containing only one window. I'm not certain if the issue is with PyQt or Qt or the input source itself, but it doesn't appear to be with python as a Tkinter app worked okay. Any answers would be great, but if anyone could suggest where to find a solution that would also be helpful. This is a pretty obscure bug, but finding a solution or work-around is important to the application I'm developing. Thank you.
