Although Justin’s issue seems more like a hanging problem and not a crash problem I’ll provide some knowledge I had recently that might be related?
I had a recent experience with a user using Slicer 4.10.0 on Windows 10 where Slicer would consistently crash after the following:
a=qt.QFileDialog()
a.getOpenFileNames()
The native dialog would open and then after about a second it would crash with a Slicer exit abnormally message and that’s it. The icon in the Windows Taskbar would flash whenever it crashed so it seem like a Explorer issue. I was unable to replicate this issue on other Windows 10 computers with Slicer 4.10.0. I tried it again on the problem computer today, and it wasn’t crashing. Maybe something about opening dialogs to specific remembered paths that are invalid or paths with specific icons?
